![[TAGALOG] Grade 9 Math Lesson: SOLVING QUADRATIC EQUATION USING QUADRATIC FORMULA](/img/1.gif)
My math exam is tomorrow wish me luck 🍀
Goodluck, how did it go?
Update?
Mine is next week 🫡
I have a mock test tommorow tho
Mas madali akong matuto sa mga videos mo kaysa sa klase namin huhu sana matagal ko ng nakita to. Exam namin bukas sa math thank you poooo.
Ty sir Keep doing it sir 🤠👍
thank you po sir Gon! I'm sure to get higher scores in algebra now!
I had fun Learning about this Topic, Thank you so much!
Glad you enjoyed it!
Exam namin bukas, wish me luck guys 🍀
If the 9x switch to a not perfect square what will we do please explain this I'm having a hard time to find a RUclips to explain this thing.
Yeah me too I got 2r² + 11r - 15 = 0
Simple and effective.
thank you!!!
LIFE SAVIOR 😭😭
nice one sir
thank you po
learned a lot from this, thank you!
thank you also!
the answer is x=10,x=-10 and numberv 2 the answer is x=-2,x=-3
if na e transpost napo yung -2 or -3 ma chachange po yung sign into positive so x=2 na po hehe
@almamantilla bakit naman po? eh positive ang 5 at 6 so obviously positive rin ang sagot. so kapag nilipat from positive magiging negative.
@@avi_swiftiee2003tama po yung -2,-3. siguro nalito lang si @almamantilla
Answer in number one is x=-10 x=10 number two x=-3 x=-2 tysm sir
i use x = (-b ± the square root of the(b² - 4ac))÷ 2a
only applicable for trinomials
ax² + bx + c = 0
just substitute
Thank you po teacher ghon.
You're welcome 😊
my life savior i own alot from you sir
Good day po, are equations that are not written in standard form still are quadratic equation? I'm having second thoughts about this. Thanks in advance for answering.
Yes po... They are still quadratic equations. 😊
@@MathTeacherGon thanks!
As long as square is the highest exponent
Thank you for this you help me alot
most welcome!
Thank you poo naintidihan ko na ngayon
thank you po sir❤
thank you sir paka liwanag ng turo mo
welcome po
Pov: my math teacher been teaching it for a week yet i only understand on this 11:20 mins video 😂
Sir paano po pag 3xsquare minus 2X equals 0
Hi Sir Gon! Can you do a video for factoring quadratic trinomials?
Hello we have that already
Pano naman po pag may number ung x dito sa examples ng 8:00
goodluck to me tommorow😢❤
Thank you sir na gets Kona HAHAHAHA
7:53 what if po parehas negative dapat po magiging positive ang answer?
thakns sir gon
Sir thank you so much!!!!
Thank you po sir
❤️😊😊
good afternoon sir gon what is x negative csquare
1/x^2
Salamat po
Umm final answer po Yung naka box?
So helpful!
thank you
Pano ba mag checking???
Paano sirr pag mas mataas yung left side
heloo ser gon how abt nmn po sa pag ccheck ng answer?
reminder: focus on the video you have an exam tomorrow
3and 5
Sirrr pano sir kung sasabihin ng teacher na dapat may checking
very helpful
Glad it helped
❤
thank you!
thanks teacher for the equations
You are welcome
Solve for x:
1.) x² - 100 = 0
Solution:
(x-10)(x-10)=0
x-10=0 | x-10=0
x=10 | x=10
2. x² + 5x + 6 = 0
Solution:
(x-3)(x-2)=0
x-3=0 | x-2=0
x=3 | x=2
Correct
Sa number six po, pwede po bang baliktad, ginawa ko po kasi is (x -3) (x-4) =0
Okay lang po ba iyon?
opo pwede po
Ask ko lng Po if may solution Po ito 20-4x+x²=0 diko Po Makita Yung Factor Ng 20 na gives us a negative 4
Madali lang yan promise
Kahit ibigay ko pa sulution nyan
Re arrange mo Yan by a= b= c=
Thanks for this! Also ang sagot ko sa dalawang activities ay
1. ( x + 10 ) ( x - 10 ) = 0
x+10 = 0
x = - 10
x - 10 = 0
x = 10
2. ( x - 5 ) ( x - 3 ) = 0
x - 5 = 0
x = 5
x - 3 = 0
x = 3
Wish me luck on exam! 🎉
wow... this is correct 💯
Yeah Good luck sa exam!!
@@MathTeacherGon Thank you po!
Posible rin ba na ang sagot sa number 2 ay ganito Sir?
(x+3)(x+2)=0
x+3=0 x+3=0
x=-3 x=-2
@@MathTeacherGon
Sir gon I didn't get it can u please teach me how?
LOL
i had a fun night because of this video thank you sir, the answers are 1.) x=10, x=-10. 2.) x=-3, x=-3
welcome
keep on learning here
correct answer for #2 is x = -2, x = -3
1. X=-10,X=10
2. X=3,X=2
thst should be x=-3, x=-2 cuz the sign is +
I love u sir
thankss
2.) X² + 5x + 6 = 0
6
^
3 • 2 ‐ ❎
---
2 • 3 ‐ ✔
(X + 2)(X + 3)
for x + 2 is
x + 2 = 0 (babaliktarin mo yung 2 and 0)
and the answer is [X = - 2]
~~~~~~~~~~
for x + 3 is
x + 3 = 0 (babaliktarin mo ulit)
and the answer is
[X = - 3]
hi po sir gon, gcf po ba yun o cmf?
Number 1)
1.)x²-100=0
(x-50)|(x-2)
x=50. | x=2
Hopefully correct 😢
Nice but can u try the x²+5x+6=20 coz I still don't know😭😭
Iba na ata yan? Dapat walang number Jan sa =
ganyan din ung akin
Medyo nalito poako sa 5 and 6
I can explain that, let's say x² is A and 8x is B and then 15 is C so. Ang hahanapin mo is yung mga factors ng C NA pag na plus sa isat isa makukuha mo yung B kaya, pag finactor natin ang c. -15 x -1 = +15, -5 x -3 = 15. Pero pag e plus mo yung -5 at -3 magiging -8 ang sagot. (Rules of integers)
1. x=10,x=-10
2. x=-3,x=-2
My maths exam is tomorrow wish me luck 👀✨
pang grade 9 1st quarter lesson poba to??
Opo🙄😭😭😭
@@ixxyaajii yun o thankyou
x=10,-10
x=-2,-3
Sir, pano po kung B² + 4b - 21 = 0
Nauna po yung positive😁
(b+7)(b-3) = 0
Can l join 5:57
sino yung wala pang pasukan pinapanood to agd
1.x=10 and 2.x=3/x=2.pls is it correct.
2. ײ + 5× +6 =0
(× + 3)(× + 2) =0
× +3=0|× +2=0
× = -3 |× = -2
1. ײ -100 =0
a² - b² = (a + b) ( a - b)
(× +10) (+ -10)=0
× +10=0| × -10 =0
× = -10 |× =10
1.X^2-100=0
(X+10)(X-10)=0
X+10=0; X-10=0
X=-10;X=10
2.X^2+5x+6=0
(X+3)(x+2)=0
X+3=0; x+2=0
X=-3; x=-2
this is correct 💯
Can I ask why did u use positive sign if the given only give a negative sign
pano po ang x2-6x-135=0 hindi ko po alam pano makukuha ang negative 6 sa factor ng 135 :((((
pls help po :(((
15.-9
Sir, Ask ko lang po bakit po
-3, -2 ung sagot sa No.1? I mean bakit parehas silang may minus? Thanks if nasagot
Tinaranspose (ililipat) po kasi ung mga terms kaya po mag iiba ung sign
Love ❤️ math
bakit po naging - 4 san po yung 4 galing????
yung sa example #2 ba or #3
Akala kopo gcf yung kinukuha sa given
1st watch di ko pa maintindihan rereply ako dito pag i get it na
SLAY GETS KO NA THANKS
My math exam is in... approximately 9 hours, well..wish me luck!!❤
