Answer:

A) 8x^2 - 14x -15

B)(x + 2) (x + 3)

Step-by-step explanation:

A)

So first you would multiply the two together

8x^2 - 20x + 6x - 15

then simplify

8x^2 - 14x -15

B) so first you would take out how many times x^2 can be put in

(x + 2) (x + 3)

then you would just check to be sure

x^2 + 3x +2x +6

x^2 + 5x + 6
