Question

Multiply.

(x - 7)(x - 10)
A) 2x + 70
B) x2 + 70
C) x2 - 70
D) x2 - 17x + 70

Answer 1

The answer is D. The easiest way to see this is by using the FOIL method.
First
Outside
Inside
Last. So the first is x2, the outside is -10x, the inside is -7x, and the last is 70. So it would be x2-17x+70
