Question

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.

Answer 1

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

Answer 2

i cannot make heads or tails of this question

Answer 3

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
\[(x-7)^2=x^2-14x+49\]

Answer 4

ohhhh. thank you!
