x^2-x+0.42=0

Solution for x^2-x+0.42=0 equation:

Simplifying
x2 + -1x + 0.42 = 0

Reorder the terms:
0.42 + -1x + x2 = 0

Solving
0.42 + -1x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.42' to each side of the equation.
0.42 + -1x + -0.42 + x2 = 0 + -0.42

Reorder the terms:
0.42 + -0.42 + -1x + x2 = 0 + -0.42

Combine like terms: 0.42 + -0.42 = 0.00
0.00 + -1x + x2 = 0 + -0.42
-1x + x2 = 0 + -0.42

Combine like terms: 0 + -0.42 = -0.42
-1x + x2 = -0.42

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 = -0.42 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -0.42 + 0.25

Combine like terms: -0.42 + 0.25 = -0.17
0.25 + -1x + x2 = -0.17

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -0.17

Can't calculate square root of the right side.
