Question

Factoring by grouping4y^2 + 8y +7y +14

Answer 1

Answer:

(4y + 7)(y + 2)

So y = -7/4 and -2

Explanation:

Given the below quadratic expression;

$4y^2+8y+7y+14$

Let's go ahead and group the factors as shown below;

$4y(y+2)+7(y+2)$

This will give us;

$(4y+7)(y+2)$

So if we equate (4y + 7) to zero, we'll have;

4y + 7 = 0

4y = -7

y = -7/4

Also,

y + 2 = 0

y = -2
