Factor the expression. 36y^2 - 84y - 147

a. (2y 7) (6y - 7)

b. 3 (2y - 7) (6y 7)

c. (2y - 7) (18y 21)

d. 3 (2y 7) (6y 7)

If you would like to factor the expression 36y^2 - 84y - 147, you can do this using the following steps:

36y^2 - 84y - 147 = 3 * (12y^2 - 28y - 49) = 3 * (6y + 7) * (2y - 7)

The correct result would be b. 3 * (6y + 7) * (2y - 7).

3 (12y^2-28y-49)

3 (12y^2-42y+14y-49)

3 (6y (2y-7) + 7 (2y-7))

3 (2y-7) (6y+7) ans b
