Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
63 + -8x + x2 = 0

Move the constant term to the right:

Add '-63' to each side of the equation.
63 + -8x + -63 + x2 = 0 + -63

Reorder the terms:
63 + -63 + -8x + x2 = 0 + -63

Combine like terms: 63 + -63 = 0
0 + -8x + x2 = 0 + -63
-8x + x2 = 0 + -63

Combine like terms: 0 + -63 = -63
-8x + x2 = -63

The x term is -8x.  Take half its coefficient (-4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
-8x + 16 + x2 = -63 + 16

Reorder the terms:
16 + -8x + x2 = -63 + 16

Combine like terms: -63 + 16 = -47
16 + -8x + x2 = -47

Factor a perfect square on the left side:
(x + -4)(x + -4) = -47

Can't calculate square root of the right side.
