(c+3)(c+3)=

Solution for (c+3)(c+3)= equation:

Simplifying
(c + 3)(c + 3) = 0

Reorder the terms:
(3 + c)(c + 3) = 0

Reorder the terms:
(3 + c)(3 + c) = 0

Multiply (3 + c) * (3 + c)
(3(3 + c) + c(3 + c)) = 0
((3 * 3 + c * 3) + c(3 + c)) = 0
((9 + 3c) + c(3 + c)) = 0
(9 + 3c + (3 * c + c * c)) = 0
(9 + 3c + (3c + c2)) = 0

Combine like terms: 3c + 3c = 6c
(9 + 6c + c2) = 0

Solving
9 + 6c + c2 = 0

Solving for variable 'c'.

Factor a trinomial.
(3 + c)(3 + c) = 0

Subproblem 1
Set the factor '(3 + c)' equal to zero and attempt to solve:

Simplifying
3 + c = 0

Solving
3 + c = 0

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + c = 0 + -3

Combine like terms: 3 + -3 = 0
0 + c = 0 + -3
c = 0 + -3

Combine like terms: 0 + -3 = -3
c = -3

Simplifying
c = -3
Subproblem 2
Set the factor '(3 + c)' equal to zero and attempt to solve:

Simplifying
3 + c = 0

Solving
3 + c = 0

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + c = 0 + -3

Combine like terms: 3 + -3 = 0
0 + c = 0 + -3
c = 0 + -3

Combine like terms: 0 + -3 = -3
c = -3

Simplifying
c = -3
Solution
c = {-3, -3}
