Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-72.25' to each side of the equation.
72.25 + 8.8x + -72.25 + x2 = 0 + -72.25

Reorder the terms:
72.25 + -72.25 + 8.8x + x2 = 0 + -72.25

Combine like terms: 72.25 + -72.25 = 0.00
0.00 + 8.8x + x2 = 0 + -72.25
8.8x + x2 = 0 + -72.25

Combine like terms: 0 + -72.25 = -72.25
8.8x + x2 = -72.25

The x term is 8.8x.  Take half its coefficient (4.4).
Square it (19.36) and add it to both sides.

Add '19.36' to each side of the equation.
8.8x + 19.36 + x2 = -72.25 + 19.36

Reorder the terms:
19.36 + 8.8x + x2 = -72.25 + 19.36

Combine like terms: -72.25 + 19.36 = -52.89
19.36 + 8.8x + x2 = -52.89

Factor a perfect square on the left side:
(x + 4.4)(x + 4.4) = -52.89

Can't calculate square root of the right side.
