How many real number solutions does the equation have?
-8x^2-8-2=0
o solutions
1
2
infinitely many
I get -1/2 so would it be 2?

I figured the discriminant at 244 so infinite?
review the discriminant. If it is positive, there are two real roots.
In this case, b^2-4ac = 0, so there is but one root.
-8x^2-8x-2 = -2(2x+1)^2
How ever did you come up with a discriminant of 244?

244 was on the wrong problem - this one was 0
