Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-43' to each side of the equation.
43 + 13x + -43 + x2 = 0 + -43

Reorder the terms:
43 + -43 + 13x + x2 = 0 + -43

Combine like terms: 43 + -43 = 0
0 + 13x + x2 = 0 + -43
13x + x2 = 0 + -43

Combine like terms: 0 + -43 = -43
13x + x2 = -43

The x term is 13x.  Take half its coefficient (6.5).
Square it (42.25) and add it to both sides.

Add '42.25' to each side of the equation.
13x + 42.25 + x2 = -43 + 42.25

Reorder the terms:
42.25 + 13x + x2 = -43 + 42.25

Combine like terms: -43 + 42.25 = -0.75
42.25 + 13x + x2 = -0.75

Factor a perfect square on the left side:
(x + 6.5)(x + 6.5) = -0.75

Can't calculate square root of the right side.
