3x + x2 + x(-6 + x) + 35 = 0
3x + x2 + (-6 * x + x * x) + 35 = 0
3x + x2 + (-6x + x2) + 35 = 0

Reorder the terms:
35 + 3x + -6x + x2 + x2 = 0

Combine like terms: 3x + -6x = -3x
35 + -3x + x2 + x2 = 0

Combine like terms: x2 + x2 = 2x2
35 + -3x + 2x2 = 0

Solving
35 + -3x + 2x2 = 0

Solving for variable 'x'.

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

Divide each side by '2'.
17.5 + -1.5x + x2 = 0

Move the constant term to the right:

Add '-17.5' to each side of the equation.
17.5 + -1.5x + -17.5 + x2 = 0 + -17.5

Reorder the terms:
17.5 + -17.5 + -1.5x + x2 = 0 + -17.5

Combine like terms: 17.5 + -17.5 = 0.0
0.0 + -1.5x + x2 = 0 + -17.5
-1.5x + x2 = 0 + -17.5

Combine like terms: 0 + -17.5 = -17.5
-1.5x + x2 = -17.5

The x term is -1.5x.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5x + 0.5625 + x2 = -17.5 + 0.5625

Reorder the terms:
0.5625 + -1.5x + x2 = -17.5 + 0.5625

Combine like terms: -17.5 + 0.5625 = -16.9375
0.5625 + -1.5x + x2 = -16.9375

Factor a perfect square on the left side:
(x + -0.75)(x + -0.75) = -16.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
