Describe the solutions to the quadratic equation
x^2+6x+9=0
a. 1 rational (double) root
b. 2 rational roots
c. 2 irrational roots
d. 2 complex roots

Answer 1

Are you familiar with the quadratic formula?

Answer 2

The part of the quadratic formula in the radical, b^2 - 4ac, tells you what type of solution you get.

Answer 3

in simpler form the equation would look like (x+3) (x+3) or (x+3)^2.
using b^2-4ac you will get 0.
Answer I would say is A.
