Question 46159: My question is relating to 5x=-4x^2-2
I know I use the qadratic equation of x= -b+- b^2-4ac/2a. I can't put the square root sign in the fornula.
anyways, near the end I have a - on the top and bottom. do i only use the (i) on the top, or both? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Let's see.
Rewrite in standard form.
You are correct in using the quadratic formula because this does not factor. Here, a = 4, b = 5, and c = 2
