Question
I am supposed to use the quadratic formula to solve this equation:

x^2-5x= -10

Answer
To use the quadratic equation, put it in its proper form.
That would be x² - 5x + 10 = 0.

Thus, we have a=1, b=-5, and c=10.

The quadratic equation is (-b±√(b²-4ac))/(2a).

Using the data gives, that is (5±√(25-40))/2.

That is, (5±√-15)/2.

If you have gotten to complex numbers, the squareroot exists and is (5±√15•i)/2.

If your only dealing with real numbers, it has no factors.
