5x^2-10x+8=0

Solution for 5x^2-10x+8=0 equation:

Simplifying
5x2 + -10x + 8 = 0

Reorder the terms:
8 + -10x + 5x2 = 0

Solving
8 + -10x + 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'.
1.6 + -2x + x2 = 0

Move the constant term to the right:

Add '-1.6' to each side of the equation.
1.6 + -2x + -1.6 + x2 = 0 + -1.6

Reorder the terms:
1.6 + -1.6 + -2x + x2 = 0 + -1.6

Combine like terms: 1.6 + -1.6 = 0.0
0.0 + -2x + x2 = 0 + -1.6
-2x + x2 = 0 + -1.6

Combine like terms: 0 + -1.6 = -1.6
-2x + x2 = -1.6

The x term is -2x.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2x + 1 + x2 = -1.6 + 1

Reorder the terms:
1 + -2x + x2 = -1.6 + 1

Combine like terms: -1.6 + 1 = -0.6
1 + -2x + x2 = -0.6

Factor a perfect square on the left side:
(x + -1)(x + -1) = -0.6

Can't calculate square root of the right side.
