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

Divide each side by '25'.
-1.68 + -1.2x + x2 = 0

Move the constant term to the right:

Add '1.68' to each side of the equation.
-1.68 + -1.2x + 1.68 + x2 = 0 + 1.68

Reorder the terms:
-1.68 + 1.68 + -1.2x + x2 = 0 + 1.68

Combine like terms: -1.68 + 1.68 = 0.00
0.00 + -1.2x + x2 = 0 + 1.68
-1.2x + x2 = 0 + 1.68

Combine like terms: 0 + 1.68 = 1.68
-1.2x + x2 = 1.68

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 = 1.68 + 0.36

Reorder the terms:
0.36 + -1.2x + x2 = 1.68 + 0.36

Combine like terms: 1.68 + 0.36 = 2.04
0.36 + -1.2x + x2 = 2.04
