Hi,

x^2- 3x= -5 

x^2 - 3x + 5 = 0    | Putting into ax^2 + bx + c = 0  Format

Quadratic formula

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

x+=+%283+%2B-+sqrt%28+9-4%2A1%2A5+%29%29%2F%282%29+

x+=+%283+%2B-+sqrt%28-11+%29%29%2F%282%29+

x+=+%283+%2B-+sqrt%28%28-1%29%2A11+%29%29%2F%282%29+   | Note i^2 = -1

x+=+%283+%2B-+sqrt%28%28i%5E2%29%2A11+%29%29%2F%282%29+

  x+=+%283+%2B-+i%2Asqrt%2811%29%29%2F%282%29+
