1.3-.8x+x^2=0

Solution for 1.3-.8x+x^2=0 equation:

Simplifying
1.3 + -0.8x + x2 = 0

Solving
1.3 + -0.8x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-1.3' to each side of the equation.
1.3 + -0.8x + -1.3 + x2 = 0 + -1.3

Reorder the terms:
1.3 + -1.3 + -0.8x + x2 = 0 + -1.3

Combine like terms: 1.3 + -1.3 = 0.0
0.0 + -0.8x + x2 = 0 + -1.3
-0.8x + x2 = 0 + -1.3

Combine like terms: 0 + -1.3 = -1.3
-0.8x + x2 = -1.3

The x term is -0.8x.  Take half its coefficient (-0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
-0.8x + 0.16 + x2 = -1.3 + 0.16

Reorder the terms:
0.16 + -0.8x + x2 = -1.3 + 0.16

Combine like terms: -1.3 + 0.16 = -1.14
0.16 + -0.8x + x2 = -1.14

Factor a perfect square on the left side:
(x + -0.4)(x + -0.4) = -1.14

Can't calculate square root of the right side.

The solution to this equation could not be determined.
