Question

Completely factor the problem, following this example: (a + b)(a - b)
x^(2) - 121

Answer 1

*x^2 - 121

Answer 2

\(\bf x^2-121 \implies x^2-11^2\\
(a-b)(a+b) = (a^2-b^2)\)

Answer 3

(x+11)(x-11)

sorry devided by 2 instead of squared

Answer 4

so the answer is (x+11)(x-11) I'm really sorry, I'm super confused

Answer 5

that looks ok, unless you're required to expand to standard form

Answer 6

I think they'll accept it. Thank you everyone(:
