(x + -3)(x + 2) = 63

Reorder the terms:
(-3 + x)(x + 2) = 63

Reorder the terms:
(-3 + x)(2 + x) = 63

Multiply (-3 + x) * (2 + x)
(-3(2 + x) + x(2 + x)) = 63
((2 * -3 + x * -3) + x(2 + x)) = 63
((-6 + -3x) + x(2 + x)) = 63
(-6 + -3x + (2 * x + x * x)) = 63
(-6 + -3x + (2x + x2)) = 63

Combine like terms: -3x + 2x = -1x
(-6 + -1x + x2) = 63

Solving
-6 + -1x + x2 = 63

Solving for variable 'x'.

-69 + -1x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '69' to each side of the equation.
-69 + -1x + 69 + x2 = 0 + 69

Reorder the terms:
-69 + 69 + -1x + x2 = 0 + 69

Combine like terms: -69 + 69 = 0
0 + -1x + x2 = 0 + 69
-1x + x2 = 0 + 69

Combine like terms: 0 + 69 = 69
-1x + x2 = 69

The x term is -1x.  Take half its coefficient (-0.5).
