Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-83' to each side of the equation.
83 + 17x + -83 + x2 = 0 + -83

Reorder the terms:
83 + -83 + 17x + x2 = 0 + -83

Combine like terms: 83 + -83 = 0
0 + 17x + x2 = 0 + -83
17x + x2 = 0 + -83

Combine like terms: 0 + -83 = -83
17x + x2 = -83

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 = -83 + 72.25

Reorder the terms:
72.25 + 17x + x2 = -83 + 72.25

Combine like terms: -83 + 72.25 = -10.75
72.25 + 17x + x2 = -10.75

Factor a perfect square on the left side:
(x + 8.5)(x + 8.5) = -10.75

Can't calculate square root of the right side.
