x^2-x=-36

Solution for x^2-x=-36 equation:

Simplifying
x2 + -1x = -36

Reorder the terms:
-1x + x2 = -36

Solving
-1x + x2 = -36

Solving for variable 'x'.

Reorder the terms:
36 + -1x + x2 = -36 + 36

Combine like terms: -36 + 36 = 0
36 + -1x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-36' to each side of the equation.
36 + -1x + -36 + x2 = 0 + -36

Reorder the terms:
36 + -36 + -1x + x2 = 0 + -36

Combine like terms: 36 + -36 = 0
0 + -1x + x2 = 0 + -36
-1x + x2 = 0 + -36

Combine like terms: 0 + -36 = -36
-1x + x2 = -36

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -36 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -36 + 0.25

Combine like terms: -36 + 0.25 = -35.75
0.25 + -1x + x2 = -35.75

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -35.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
