Which is a solution of 2x(8x + 5) (7x – 13) = 0?

Step-by-step explanation:

This has 3 solutions

2x = 0                          Divide by 2

x = 0

8x + 5 = 0                   Subtract 5 from both sides

8x = - 5                       Divide by 8

x = - 5/8

x = -0.625

7x - 13 = 0                   Add 13 to both sides

7x = 13                         Divide by 7

x = 13/7

x = 1.86

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
