-4x = -2x2 + 30 


Add +4x to each side of the equation.


-4x + 4x = -2x^2 + 30 + 4x

-4x + 4x = 0

Therefore:

-2x^2 + 30 + 4x = 0

Rearrange the quadratic equation:


-2x^2 + 4x + 30 = -

Divide each item by -2

-2x^2/-2 = x^2

4x/-2 = -2x

30/-2 = -15

Now we have:

x^2 - 2x - 15 = 0

Factor:


(x + 3)(x - 5) = 0



Answer:

x = -3, 5
