Solving Quadratic Equations Graphically
Просмотров 314 года назад
This video uses the GeoGebra graphing calculator to shows how to find the solutions (roots, x-intercepts, zeros) of quadratic equations - written in standard form. Recall, the quadratic formula can find all solutions - real or complex - of any quadratic equation. Graphing a quadratic equation allows us to find all real solutions of a quadratic equation. If there are no real solutions to the qua...
AP Calculus AB Review

Thanks a lot for the help ❤️
Not quite helpful ,thanks for your share
Thank you!
i know this is an old video but thank you so much! i thought i wouldn't be able to finish my last unit of statistics without a graphing calculator but now i'm able to without one :)
Thanks for giving the exercise
easy
15 minutes until the test? I suppose I could study for the first time this year
Test in 38 minutes… im kinda fkd
Sike im get a 3 aby being lucky

This video was so helpful though ughhh. So much clarity
My school starts in 2 days and I’m going straight into calc ab and I’m scared. How was it for you? I’m trying to prepare by learning trig identities and creating a better knowledge of the unit circle but what advice would you give?
@@valzthegoat6933 oh i am really late but how was your exam mine was shit i got 2. i should have taken sat this year and ap next year( i am 16) but still it was an experience and this year we are taking trig more detailed so it would be easier for me AND FOR ANYONE IF YOU ARE GOING TO TAKE ANY AP EXAM DONT LEAVE TO LAST 2 WEEKS!!
Whose here for the 2022 exam
Thank you!!
why was this recommended to me
I see blood coming down from my nose.
Definitely don’t have my class final tomorrow and watching this because I forgot everything before integrals. You already know I’ll be back the night before the AP test
Why didn’t u study through out the year then
