Question

Use the distributive property to find the product.

(t – 1)(t + 8)
A.
t2+ 7t – 8
B.
t2 – 7t – 8
C.
t2 - 8t + 7
D.
t2+ 8t – 7

Answer 1

Use the Foil Method:

First: t x t =t^2
Outsides: t x 8 = 8t
Insides: -1 x t = - t
Lasts: 8 x -1 = -8

so you'll have t^2 + 8t - t - 8, simplify it more: t^2 + 7t - 8, A.
