Answer 1

is that x squared minus 13?

Answer 2

Yeeesss ma'am

Answer 3

okay so here's how it goes

Answer 4

\[x^2 - 13 \]
\[(x+5)^2 - 13\]
\[x^2 + 20x + 25 - 13\]

what are the answer choices?

Answer 5

−12
3
−13
8

How did you get 20x ?

Answer 6

because of (x+5)(x+5) since it's squared

Answer 7

Okay , that makes sense
