Solving
3 + -2.4c + (6c2) = -6

Solving for variable 'c'.

Reorder the terms:
3 + 6 + -2.4c + (6c2) = -6 + 6

Combine like terms: 3 + 6 = 9
9 + -2.4c + (6c2) = -6 + 6

Combine like terms: -6 + 6 = 0
9 + -2.4c + (6c2) = 0

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

Divide each side by '6'.
1.5 + -0.4c + c2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + -0.4c + -1.5 + c2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + -0.4c + c2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + -0.4c + c2 = 0 + -1.5
-0.4c + c2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
-0.4c + c2 = -1.5

The c term is -0.4c.  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.
-0.4c + 0.04 + c2 = -1.5 + 0.04

Reorder the terms:
0.04 + -0.4c + c2 = -1.5 + 0.04

Combine like terms: -1.5 + 0.04 = -1.46
0.04 + -0.4c + c2 = -1.46

Factor a perfect square on the left side:
((c) + -0.2)((c) + -0.2) = -1.46

Can't calculate square root of the right side.

The solution to this equation could not be determined.
