Find the discriminant and the number of real roots for this equation 4x^2+16x+16=0

2 real roots: x = -2 multiplicity 2.

Step-by-step explanation:

The discriminant = b^2 - 4ac

= 16^2 - 4*4*16

= 0

This means there are duplicate roots, 2 roots having the same value.

4x^2+16x+16=0

(2x + 4)(2x + 4) = 0

x = -2 , -2.
