Hi,
x^2-3x=-6
Put into the following form:
x^2 - 3x + 6 = 0
.
Using the quadratic formula: In this case a = 1, b = -3 and c = 6
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
.
x+=+%283+%2B-+sqrt%28+%28-3%29%5E2-4%2A6+%29%29%2F2+
.
x+=+%283+%2B-+sqrt%28-15%29%29%2F2+
Note: there are no solutions among real numbers
.
In the field of imaginary numbers: solution would be as follows
x+=+%283+%2B-+i%2Asqrt%2815%29%29%2F2+
