Solution for 20x^2+1=8x equation:


Simplifying
20x2 + 1 = 8x

Reorder the terms:
1 + 20x2 = 8x

Solving
1 + 20x2 = 8x

Solving for variable 'x'.

Reorder the terms:
1 + -8x + 20x2 = 8x + -8x

Combine like terms: 8x + -8x = 0
1 + -8x + 20x2 = 0

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

Divide each side by '20'.
0.05 + -0.4x + x2 = 0

Move the constant term to the right:

Add '-0.05' to each side of the equation.
0.05 + -0.4x + -0.05 + x2 = 0 + -0.05

Reorder the terms:
0.05 + -0.05 + -0.4x + x2 = 0 + -0.05

Combine like terms: 0.05 + -0.05 = 0.00
0.00 + -0.4x + x2 = 0 + -0.05
-0.4x + x2 = 0 + -0.05

Combine like terms: 0 + -0.05 = -0.05
-0.4x + x2 = -0.05

The x term is -0.4x.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4x + 0.04 + x2 = -0.05 + 0.04

Reorder the terms:
0.04 + -0.4x + x2 = -0.05 + 0.04

Combine like terms: -0.05 + 0.04 = -0.01
0.04 + -0.4x + x2 = -0.01

Factor a perfect square on the left side:
(x + -0.2)(x + -0.2) = -0.01

Can't calculate square root of the right side.

The solution to this equation could not be determined.
