Question

(7b + 3)(b − 1) = 0
By factoring

Answer 1

Explanation:

it is already factored.

there are therefore 2 solutions to this : each one turns one of the factors to 0, which makes the result of the multiplication 0 and therefore the equation true

7b + 3 = 0

7b = -3

b = -3/7

b - 1 = 0

b = 1
