use the discriminant to describe the roots of each equation. then select the best description.

2x^2 + 7x + 6 = 0

x^2 - 5x - 4 = 0

6x^2 + 13x + 6 = 0

16x^2 + 8x + 1 = 0

2x^2 + 7x + 6 = 0

2m^2 + 3 = m

2 = x^2 + 5x

x^2 + 9x + 14 = 0

the options are:

double root
real and rational roots
real and irrational roots
non-real roots
