Answer 2

FOIL stands for: First, Outer, Inner, Last

First: first terms are x and x, they multiply to x*x = x^2

Outer: outer terms are x and 3, they multiply to x*3 = 3x

Inner: inner terms are -2 and x, they multiply to -2*x = -2x

Last: last terms are -2 and 3, they multiply to -2*3 = -6

Now add up the last 4 results to get

x^2 + 3x + (-2x) + (-6)

x^2 + 3x - 2x - 6

x^2 + 1x - 6

x^2 + x - 6

Answer 3

So (x-2)(x+3) expands out to x^2 + x - 6
