Algebra 2 - Completing the Square

Рет қаралды 330,682

Күн бұрын

Weeeee're BACK! This time with some vintage Yay Math in class, discussing some high level completing the square. What makes it high level is that on our last problem, we handle a quadratic equation with a leading coefficient. We address how factoring would be a great method, as well as the quadratic formula, IF POSSIBLE. When not, completing the square to the rescue. YAY MATH!

I'm jealous for the students, they have no idea how lucky they are to have a teacher like you.

"jealous for"? Makes no sense whatsoever. Maybe you mean "envious of". Maybe there's a KZfaq English teacher out there who is as good as this maths teacher. Raise your game.

Good explainer! I've watched other videos teach 'completing the square' without explaining the (b/2)², or the (b/2) shortcut, making them mathemagicians not teachers. Thanks for the video! In grad school econometrics, the prof put a three-board problem on the white board. One of the top math students said "I see where you began, and I see where the answer is, but how did you get from the beginning to the answer? The prof replied "Do you really want to know??" I almost blurted out 'No. It was an effin' rhetorical question!'

@harivonwintr 7 жыл бұрын

On the last equation, how do you know when it's possible to factor and when not. Because the way I learned was that you had to get a number that could be multiplied into C and also be added together to make B. How does 3+1 = 5x?? If I had something like 2x2 -16x + 3 would the same rule apply?

@timonofathens8645 5 жыл бұрын

He skips some steps. 2x2-5x+3=0 a b c STEP 1 ac=2*3=6 Factors of ac: (1,6) (-1,-6) (2,3) (-2,-3) The pair of factors which added together equals -5 is (-2,-3) STEP 2 You plug those two numbers into the equation replacing b ,in this case, -5. The equation becomes: 2x2 -2x-3x +3 = 0 STEP 3 Here comes the factorization!! Split the equation in half, factorizing the first and second half separately. 2x2-2x -3x+3= 0 2x(x-1) -3(x-1) = 0 STEP 4 This next step will bring you to where he starts ;) (2x-3) (x-1) = 0 Hope this helps! Peace. God bless you.

When I teach completing the square I start with coefficients only. For instance 1+4-5=0 which can be changed to1+4=5. Now take half of 4 and square it to get 1+4+4 = 5 so you have to add 4 to the right side because you did so on the left which becomes 9=9 since 9 is 3 times three so the formula becomes (x-3)squared -9 =0.
