3x^2 + 8 = -4
Answered by Steve
no solution. I suspect a typo. Assuming an 8x, we have

(x+2)(3x+2) = 0
Answered by Janae
there isn't any 8x it just say solve for x
Answered by Steve
well, shoot. Then just subtract 8 from both sides to get

3x^2 = -12
x^2 = -4

there is no real solution, since x^2 is never negative for real x.

If you allow complex solutions, then x = 2i or -2i. I believe this is from Algebra I, and should not be posing a difficulty for someone in Pre-Cal...
