Hi

Using the quadratic formula to solve the equation.

x%5E2-3x=-7

 x^2 - 3x + 7 = 0

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%283+%2B-+sqrt%28+-19+%29%29%2F%282%29+

x+=+%283+%2B-+i%2Asqrt%2819+%29%29%2F%282%29+

The solution set is %283%2Bi%2Asqrt%2819+%29%29%2F%282%29, %283-i%2Asqrt%2819+%29%29%2F%282%29+
