## anonymous 4 years ago What does (coefficient of x/2)^2 = last term mean? For ex. (x-1)^2 = (x-1)(x-1) = x^2 -2x + 1 (right side is (coefficient of x/2)^2 = last term.

Additionally, (x-7)^2 = (x-7)(x-7) = x^2 - 14x + 49 is true that (coefficient of x/2)^2 = last term.

i cannot make heads or tails of this question

ooooooooooooh yes i can i think if you have for example $x^2-14x+49$ then the "coefficent of the x term" is $-14$ and $-\frac{14}{2}=-7$ so you get $(x-7)^2=x^2-14x+49$

ohhhh. thank you!
