Dear sir please explain the meaning of the signs which you use in question because literally I don't get that. Algebra is looking very hard all the equations you made while In a question that is very tough for me to understand them please🙏 sir explain each small points
Bhai simple h pehle roughly do graph bna lo jo x axis se interrsect hote h root point pr. Ab jo equation h usme x ki value 0 rakhdo agar answer positive aaya ki negative. Ab y tumko Positive ya negative aata h to teen point tumko pta chal gye h A(Alfpha, 0), B(Beta, 0) and C(0, Y cordinate) ab teeno point se graph ko bna ke dekhlo.
when y is in the positive section of the check the diagram you will see that the x is going away in the left direction of the alpha and alpha lies in -ve x and as the y will increase the magnitude of x will increase but as it is in the -ve x half the number there will go smaller and smaller. hence alpha will be greater for the simple reason -4 is greater than -14 because of the -ve sign similarly in case on the other side as y is +ve the line is going +ve after beta ( positive meaning crossing the x and coming to the positive section of y) in this case also the magnitude is increasing but there is no -ve sign as it is +ve x , so for simple reason 14>4 x will be greater than the beta

Bro understand as on x axis basis like if we move towards minus like -1,-2,-3,-4 then value is Decreasing so first x will always be less than alpha and just reverse for the positives
starting my CAT journey wish me luck
How was your result?
@@Priyanshu_Pandey01Sb students ko iss time Algebra chlri😂

Best of luck bhai😶😶😶😶😶😶
its been 2 years
how are you? what’s up?
Sir where were you sir. In my whole life i was not able to solve equation but you made it soooooo easy for me in just 5 mins. Thankyouu

will always be grateful to uplift our knowledge sir. please keep sharing videos for this year's imp questions.
Great source for quick revision! ♥️

They are Explained in "Sets" part... Union and Intersection
Thank you Sir, your videos are a blessing.
sir I don't know anything about graphs. From where should I study the basics
Simple middle term factors ❤
NICE EXPLANATION!!
great sir explanation is very crystal clear sir.........
Thanks you sir
I have been binge watching your algebra playlist,will i able to crack cat lvl questions with this??\
WHich topic in algebra should i give more importance to?
Have you found out?????
Very nice
thankyou sir,..........
GREAT SIR
Don't know anything about graphs and that XE ( ) and U ( )
Last question me graph nhi samjh aaya upar kyu bana jab y < o tha
same bro muje bi btana pta chla toh
Upward and downward graph depends on 'a' i.e. coefficient of x^2 , here a>0 therefore upward graph
Bhai simple h pehle roughly do graph bna lo jo x axis se interrsect hote h root point pr. Ab jo equation h usme x ki value 0 rakhdo agar answer positive aaya ki negative.

Amazing sir
thank u so much sir❤
Beautifully explained. Thankyou so much sir
You're giving CAT 23 or 24?
Cat 69
Sir, when a>0 and y>0 , why is xbeta ? this part is not clear to me.
when y is in the positive section of the check the diagram you will see that the x is going away in the left direction of the alpha and alpha lies in -ve x and as the y will increase the magnitude of x will increase but as it is in the -ve x half the number there will go smaller and smaller. hence alpha will be greater for the simple reason -4 is greater than -14 because of the -ve sign
similarly in case on the other side as y is +ve the line is going +ve after beta ( positive meaning crossing the x and coming to the positive section of y) in this case also the magnitude is increasing but there is no -ve sign as it is +ve x , so for simple reason 14>4
x will be greater than the beta
sir why graph upward when a>o and similarly vice versa?
its an result derived we need to remember those. take graph paper and try to plot graph with A less than and greater than 0 you will get to know
Coefficient of x^2 is a. So, if a +ve upwards, -ve downwards.
If a>0 then ax^2 increases with an increase in x and x^2 term dominates the bx+c term, hence the curve will be upwards

How to know the part of bracket, if that is included or excluded?
It depends on the inequality sign.
hey guys serious question here, why is your channel name rodha?
hope so such advanced level ques won't come in cat
🤣🤣@am1859
Give a video on total modulus and inequities
Ye b hai kya syllabus me
What was your cat score????
Why (x-alpha) (x-beta) =0 ?
Alpha and beta are the zeros of the equation and that's the standard for of writing zeros.
If alpha and beta are positive zeros then (x-alpha). If negative then (x+alpha)

16:56 didn't understand completely.can anyone plz explain????
Bro understand as on x axis basis like if we move towards minus like -1,-2,-3,-4 then value is Decreasing so first x will always be less than alpha and just reverse for the positives
In positive side x will always be greater than Beta this case is for y>0
Sir ye graph kuch samjh nhi aaraha he
I think graph is wrong a 23:15
No here a>0 so the graph is correct 💯
I thing sir deletes many videos from different topics....
No no. I have not deleted a single video yaar.
