Question

How do you simplify (x-8)^2

Answer 1

(a - b)^2 = a^2 - 2ab + b^2. given that a = x and b = 8, can you solve it from there?

Answer 2

you don't
you can however "multiply"
start with
\[(x-8)(x-8)\] then multiply it out

Answer 3

We meet again, satellite! ☺

Answer 4

\[x ^{2} - 2*x*8 + 8^{2}\]

Answer 5

That simplifies to \[x^2 -16x + 64\]. and there you go.
