Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-144.5' to each side of the equation.
144.5 + 17x + -144.5 + x2 = 0 + -144.5

Reorder the terms:
144.5 + -144.5 + 17x + x2 = 0 + -144.5

Combine like terms: 144.5 + -144.5 = 0.0
0.0 + 17x + x2 = 0 + -144.5
17x + x2 = 0 + -144.5

Combine like terms: 0 + -144.5 = -144.5
17x + x2 = -144.5

The x term is 17x.  Take half its coefficient (8.5).
Square it (72.25) and add it to both sides.

Add '72.25' to each side of the equation.
17x + 72.25 + x2 = -144.5 + 72.25

Reorder the terms:
72.25 + 17x + x2 = -144.5 + 72.25

Combine like terms: -144.5 + 72.25 = -72.25
72.25 + 17x + x2 = -72.25

Factor a perfect square on the left side:
(x + 8.5)(x + 8.5) = -72.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
