Step-by-step explanation:

To solve a non-factorable quadratic equation in the form of , you need to use the quadratic formula where :

Because of the sign, quadratic equations always have two solutions, whether both are real, only one is real, or both are complex (in the form of where is the real part and is the imaginary part where ). In this case, because the discriminant is positive (defined as ), then there are 2 real solutions.

The solutions are thus
