10x^2-41x-156

Explanation:

Foil stands for first, outside, inside, last.

In this questions, there are two terms, 2x-13 and 5x+12

First means you multiply the first set of values, 2x and 5x
2x*5x=10x^2

Outside means you multiply the outer values, 2x and 12
2x*12=24x

Inside means you multiply the inner values, -13 and 5x
-13*5x=-65x

Last means you multiply the last values, -13 and 12
-13*12=-156

Now you can put those into one expression and simplify
10x^2+24x-65x-156
10x^2-41x-156
