Solving for variable 'x'.

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

Divide each side by '25'.
0.72 + 1.2x + x2 = 0

Move the constant term to the right:

Add '-0.72' to each side of the equation.
0.72 + 1.2x + -0.72 + x2 = 0 + -0.72

Reorder the terms:
0.72 + -0.72 + 1.2x + x2 = 0 + -0.72

Combine like terms: 0.72 + -0.72 = 0.00
0.00 + 1.2x + x2 = 0 + -0.72
1.2x + x2 = 0 + -0.72

Combine like terms: 0 + -0.72 = -0.72
1.2x + x2 = -0.72

The x term is 1.2x.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2x + 0.36 + x2 = -0.72 + 0.36

Reorder the terms:
0.36 + 1.2x + x2 = -0.72 + 0.36

Combine like terms: -0.72 + 0.36 = -0.36
0.36 + 1.2x + x2 = -0.36

Factor a perfect square on the left side:
(x + 0.6)(x + 0.6) = -0.36

Can't calculate square root of the right side.

The solution to this equation could not be determined.
