Use discriminant if the given equation can be factored, otherwise, use  he quadratic formula to solve this equation.

discriminant = b² - 4ac

In this case the discriminant is greater than zero, so it can be factored:
 8 (x-3/4) (x+4)

In case you are asked the roots of this equation, equate the factors to zero, then solve fore x:

the roots are:
x-3/8 = 0
x = 3/8

x+4=0
x = -4
0
