Dude you don't understand how much this guy has saved my life in math. I almost want to cry bro. I was so frustrated and I hated math, and it seemed like nothing but a dark tunnel with no way out. But this guy came in and everythings coming together. He's always the one who comes in and gives hope to us math students. This guy is the most underrated teacher in all of KZbin

How did you get 2 as your final answer!?

[@MAYONNAISEMOOSE]

First you use the quadratic equation then you use the 0 property -- that is, when you have to sets of equations that equal 0.

[@mohammedkhaled2456]

It turned out that x-int = (2, 0) and the y -int = (0, 4) and the vertex is (2, 0) as well ... Is it a happy face parabola that cuts the y axis at ( 0, 4 ) and the x axis at ( 2 , 0 ) which is its vertex and x axis intersection point at same time and bounces afterwards off ( 2 , 0) to change its direction upwards towards the infinity . Its domain is ( negative infinity , positive infinity ) and its range is ( 0 , positive infinity ) .

At 3:41, you said -2 and -2 could add to -4...? How? Or are you just reading across the lines as -2-2?

The problem was 2x^2-16x+29 I substituted the x’s with 0’s that’s how I got 29.

Same I’m in 7th grade and this is part of the honors course which is the highest level course in my school

[@johnricson2667]

what if it's y=(x+1)^2 how do you get the x intercept?

[@somerandomguy92]

Simple factoring; You want y to be 0 since you're looking for the x intercepts Therefore you have (x+1)(x+1)=0 The one solution that would make this equal to 0 is if x=-1 That means you only have one x intercept, at (-1,0)

[@florindelalba7639]

would there not be two x int. ?

[@cowragerzzz678]

There would only be one since if both x-intercepts are the same, the graph crosses the x-axis one time, therefore having only one x-intercept

[@Ammor723]

what if it was x=-2 and x=+2, which one would be the correct x intercept?

[@SanviJaiswal-gz4el]

One would be correct sorry

[@frankj9270]

Ok now how do you solve if there is a number for A in AX^2 + BX + C

[@debbiemoran4700]

on 3:37 I dont understand where this -2 and -2 came from?

[@flawdaboyvince3176]

He can just low key play his vid in the future to his students and not have to teach

[@alynherndon7667]

Dang it cody

[@enzoerwin3464]

I’m assuming that means both the x intercepts are 2 right?

[@michaelmunoz9233]

I understand you had to factor to get -2, but why 2 times? Why was -2 in both sides of the X?

[@Udsinghkh123]

Because -2 times -2 = 4 and -2 + -2 = -4. This works with the quadratic given, so it can be used to factories it.

[@mehakverma7043]

does this work when a does not equal 1?

[@brianmclogan]

No need to work a different technique

[@vda1209]

how to solve this f(x) = (x - 5)squared

[@MayaW--arlopamperdpooch]

expand it out to be x^2 -10x +25. use a generic rectangle or the FOIL method. it is a perfect square trinomial, so x =-5. or, if you don't know that method, then use the method he shows at the end of the video (the diamond thing) you will find that -5 times -5 equals 25, and -5 plus -5 equals -10, so x = -5

[@HuaweiHuawei-oy6jt]

Sir great you are

[@drdeepajacob]

God what a life saver

[@briannabarrett3984]

Hi of course I’m horrible at math but quick question.. after factoring out and you got x-2=0 2x how did you get X=2 and not X=-2

[@Help404xyz]

If x were -2, then the equation would be -2-2=0 which isn't true as -2-2 is -4, positive 2 does make this true because 2-2=0
