x^2-0.3x+0.6=0

Solution for x^2-0.3x+0.6=0 equation:

Simplifying
x2 + -0.3x + 0.6 = 0

Reorder the terms:
0.6 + -0.3x + x2 = 0

Solving
0.6 + -0.3x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.6' to each side of the equation.
0.6 + -0.3x + -0.6 + x2 = 0 + -0.6

Reorder the terms:
0.6 + -0.6 + -0.3x + x2 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + -0.3x + x2 = 0 + -0.6
-0.3x + x2 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
-0.3x + x2 = -0.6

The x term is -0.3x.  Take half its coefficient (-0.15).
Square it (0.0225) and add it to both sides.

Add '0.0225' to each side of the equation.
-0.3x + 0.0225 + x2 = -0.6 + 0.0225

Reorder the terms:
0.0225 + -0.3x + x2 = -0.6 + 0.0225

Combine like terms: -0.6 + 0.0225 = -0.5775
0.0225 + -0.3x + x2 = -0.5775

Factor a perfect square on the left side:
(x + -0.15)(x + -0.15) = -0.5775

Can't calculate square root of the right side.

The solution to this equation could not be determined.
