Find the value of x. Use radicals as needed.

Igot -8 as an answer

Yx(2+4) so you do y times 2 then y times 4

The given  0 = x + 2 + x2 can and should be re-written as  0 = 1x^2 + 1x   + 2.   thus, a=1, b=1 and c=2.   the discriminant is b^2-4ac, or 1^2-4(1)(2), or1-8=-7.because the discriminant is negative we have two complex roots.
