Which of the following are solutions to the equation below? check all that apply. 9x^2-6x+1=7

The answer is C and D

First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0 

Then we will use the quadratic formula to find the answers.

using the Quadratic Formula where:
a = 9, b = -6, and c = -6

and the formula is 6 +-  / 2(9)
