Solve the equation by factoring 16xsquared +2x-3=0

Question

Need help solving 

Answer 1

16x^2 + 2x -3 = 0. It's just trial and error, using factors of 16, 8 and 2, 4 and 4, 16 and 1 as the coefficients of the x terms in the two factors, and same for 3's factors, 1 and 3 as the constant terms)

(8x-3)(x+1) = 0

8x-3 = 0, x+1=0

x =3/8 and -1
