select the approximate values of x that are solutions to f(x)=0 where f(x)-5x^2+8+5

F(x) = 5x^2 + 8x + 5 = 0

Quadratic Formula:
X = (-B +- sqrt(B^2-4AC))/2a
X = (-8 +- sqrt(64-100))/10 =
(-8 +- sqrt(36*(-1))/10 =
(-8 +- 6i)/10 = -0.8 +- 0.6i =
-0.8 + 0.6i, and -0.8 - 0.6i.

So we have 2 imaginary solutions.
