Answer:

2nd choice: x = -2 or x= 3/5

Step-by-step explanation:

5x² + 7x = 6

We can solve.

5xx + 7x - 6 = 0

try the diamond method first

-30 = 5*-6....   -3*10 = -30  and  -3x + 10x = 7x

So...

5xx - 3x  + 10x  - 6 = 0

x(5x - 3) + 2(5x - 3)  = 0

(x +2)(5x - 3) = 0

roots  x = -2  and x = +3/5
