5c(c-1)+3=

Solution for 5c(c-1)+3= equation:

Simplifying
5c(c + -1) + 3 = 0

Reorder the terms:
5c(-1 + c) + 3 = 0
(-1 * 5c + c * 5c) + 3 = 0
(-5c + 5c2) + 3 = 0

Reorder the terms:
3 + -5c + 5c2 = 0

Solving
3 + -5c + 5c2 = 0

Solving for variable 'c'.

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

Divide each side by '5'.
0.6 + -1c + c2 = 0

Move the constant term to the right:

Add '-0.6' to each side of the equation.
0.6 + -1c + -0.6 + c2 = 0 + -0.6

Reorder the terms:
0.6 + -0.6 + -1c + c2 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + -1c + c2 = 0 + -0.6
-1c + c2 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
-1c + c2 = -0.6

The c term is -1c.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1c + 0.25 + c2 = -0.6 + 0.25

Reorder the terms:
0.25 + -1c + c2 = -0.6 + 0.25

Combine like terms: -0.6 + 0.25 = -0.35
0.25 + -1c + c2 = -0.35

Factor a perfect square on the left side:
(c + -0.5)(c + -0.5) = -0.35

Can't calculate square root of the right side.

The solution to this equation could not be determined.
