5x^2-5x+12=0

Solution for 5x^2-5x+12=0 equation:

Simplifying
5x2 + -5x + 12 = 0

Reorder the terms:
12 + -5x + 5x2 = 0

Solving
12 + -5x + 5x2 = 0

Solving for variable 'x'.

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

Divide each side by '5'.
2.4 + -1x + x2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + -1x + -2.4 + x2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + -1x + x2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + -1x + x2 = 0 + -2.4
-1x + x2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
-1x + x2 = -2.4

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 = -2.4 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -2.4 + 0.25

Combine like terms: -2.4 + 0.25 = -2.15
0.25 + -1x + x2 = -2.15

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -2.15

Can't calculate square root of the right side.

The solution to this equation could not be determined.
