4 0
STEP-BY-STEP SOLUTION:

0 = ( 5x + 13 ) ( 3x + 7 )

0 = 15x^2 + 35x + 39x + 91

0 = 5x ( 3x + 7 ) + 13 ( 3x + 7 )

0 = ( 3x + 7 ) ( 5x + 13 )


3x + 7 = 0

3x = - 7

x = - 7 / 3


5x + 13 = 0

5x = - 13

x = - 13 / 5


ANSWER:

Therefore, there are two solutions to this problem. The answer is:

x = - 7 / 3

&

x = - 13 / 5

Hello!

if x = -3, just substitute it for x (replace the x with -3)

2 * -3 = -6

-6 + 6 = 0

I hope this helps, and have a nice day!
