Use the discriminant to describe the roots of each equation. Then select the best description.

7x2 + 3 = 8x

double root

real and rational root

real and irrational root

imaginary root

imaginary root

Step-by-step explanation:

7x^2 + 3 = 8x

Subtract 8x from each side

7x^2 - 8x + 3 = 8x-8x

7x^2 - 8x+3 = 0

This is in the form ax^2 + bx+c

The discriminant is b^2 - 4ac

a=7 b=-8 c=3

b^2-4ac = (-8) ^2 - 4 (7) (3) = 64 - 84 = - 20

Since this is negative, we have imaginary roots
