Step-by-step explanation:

Factoring out the greatest common factor in each case, we can simplify the process of finding the non-zero solution. The solutions are the values of the variable that make the factors be zero.

1) 7x^2 +2x = 0 = (x)(7x +2)   ⇒   x = 0; x = -2/7

__

2) 5b^2 -10b = 0 = (5b)(b -2)   ⇒   b = 0; b = 2

__

3) 3d^2 -d = 0 = d(3d -1)   ⇒   d = 0; d = 1/3

__

4) 17x^2 +51x = 0 = 17x(x +3)   ⇒   x = 0; x = -3
