64 + -11x + x2 = 0

Solving
64 + -11x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-64' to each side of the equation.
64 + -11x + -64 + x2 = 0 + -64

Reorder the terms:
64 + -64 + -11x + x2 = 0 + -64

Combine like terms: 64 + -64 = 0
0 + -11x + x2 = 0 + -64
-11x + x2 = 0 + -64

Combine like terms: 0 + -64 = -64
-11x + x2 = -64

The x term is -11x.  Take half its coefficient (-5.5).
Square it (30.25) and add it to both sides.

Add '30.25' to each side of the equation.
-11x + 30.25 + x2 = -64 + 30.25

Reorder the terms:
30.25 + -11x + x2 = -64 + 30.25

Combine like terms: -64 + 30.25 = -33.75
30.25 + -11x + x2 = -33.75

Factor a perfect square on the left side:
(x + -5.5)(x + -5.5) = -33.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
