Well this looks simple. Just subsitute in the x values (the answer choices) and see if they equal 1.

idk how to with the fractions. therefore im stuck

To find the answer, just substitute in the answer choices. For example, if we were to substitute x=3/4 into the equation it would look like this:

8x^2-2x-2=1

8(3/4*3/4)-2(3/4)-2=1

8(9/16)-3/2-2=1

9/2-3/2-2=1

6/2-2=1

3-2=1

make sense?
