Question

Help I take the Math pert next week and i don't understand this

Answer 1

Understand what?

Answer 2

@masterchief609 do you know what a "perfect square trinomial" is?

Answer 3

this is a very complicated version of quadratic formula, I'll try to find a link with better explanation

Answer 4

a trinomial with perfect squares?

Answer 5

yes

Answer 6

that's all you really need, don't let others make it so complicated

Answer 7

arbershabani97 methinks is a proof

Answer 8

yep, it's just proof on how you achieved it, but it's much easier just to use the formula, by only memorizing it

Answer 9

@masterchief609 anyhow, the procedure all is doing is "completing the square"
by making the left side a perfect trinomial square

I assume you've cover "completing the square" ?

Answer 10

anyhow... need to dash..... notice the "square completion" on say step 4
tis skipping something
