Question

Simplify: (x - 8)^2

Answer 1

(a - b)^2 = a^2 - 2ab + b^2

Answer 2

x^ - 16x + 64 is what u shd get if u expand it

Answer 3

if by simplify you mean multiply.

Answer 4

binomial theorem?
\[(x-8)^2=\sum_{k=0}^{k=2}\left(\begin{matrix}2 \\ k\end{matrix}\right)x ^{2-k}-8^k\]

Answer 5

so:
\[\left(\begin{matrix}2 \\ 0\end{matrix}\right)x^{2-0}(-8)^0+\left(\begin{matrix}2 \\ 1\end{matrix}\right)x^{2-1}(-8)^1+\left(\begin{matrix}2 \\ 2\end{matrix}\right)x^{2-2}(-8)^2\]

Answer 6

\[x^2+(2)(x)(-8)+64\]

Answer 7

\[x^2-16x+64\]

Answer 8

i showed my simplifying steps

Answer 9

sorry to make it more complex than it really is
