5c^2-2c=-3

Solution for 5c^2-2c=-3 equation:

Simplifying
5c2 + -2c = -3

Reorder the terms:
-2c + 5c2 = -3

Solving
-2c + 5c2 = -3

Solving for variable 'c'.

Reorder the terms:
3 + -2c + 5c2 = -3 + 3

Combine like terms: -3 + 3 = 0
3 + -2c + 5c2 = 0

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

Divide each side by '5'.
0.6 + -0.4c + c2 = 0

Move the constant term to the right:

Add '-0.6' to each side of the equation.
0.6 + -0.4c + -0.6 + c2 = 0 + -0.6

Reorder the terms:
0.6 + -0.6 + -0.4c + c2 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + -0.4c + c2 = 0 + -0.6
-0.4c + c2 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
-0.4c + c2 = -0.6

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 = -0.6 + 0.04

Reorder the terms:
0.04 + -0.4c + c2 = -0.6 + 0.04

Combine like terms: -0.6 + 0.04 = -0.56
0.04 + -0.4c + c2 = -0.56

Factor a perfect square on the left side:
(c + -0.2)(c + -0.2) = -0.56

Can't calculate square root of the right side.

The solution to this equation could not be determined.
