16 + -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'.
3.2 + -2x + x2 = 0

Move the constant term to the right:

Add '-3.2' to each side of the equation.
3.2 + -2x + -3.2 + x2 = 0 + -3.2

Reorder the terms:
3.2 + -3.2 + -2x + x2 = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0
0.0 + -2x + x2 = 0 + -3.2
-2x + x2 = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2
-2x + x2 = -3.2

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 = -3.2 + 1

Reorder the terms:
1 + -2x + x2 = -3.2 + 1

Combine like terms: -3.2 + 1 = -2.2
1 + -2x + x2 = -2.2

Factor a perfect square on the left side:
(x + -1)(x + -1) = -2.2

Can't calculate square root of the right side.
