(x+3)(x+3)=-1

Solution for (x+3)(x+3)=-1 equation:

Simplifying
(x + 3)(x + 3) = -1

Reorder the terms:
(3 + x)(x + 3) = -1

Reorder the terms:
(3 + x)(3 + x) = -1

Multiply (3 + x) * (3 + x)
(3(3 + x) + x(3 + x)) = -1
((3 * 3 + x * 3) + x(3 + x)) = -1
((9 + 3x) + x(3 + x)) = -1
(9 + 3x + (3 * x + x * x)) = -1
(9 + 3x + (3x + x2)) = -1

Combine like terms: 3x + 3x = 6x
(9 + 6x + x2) = -1

Solving
9 + 6x + x2 = -1

Solving for variable 'x'.

Reorder the terms:
9 + 1 + 6x + x2 = -1 + 1

Combine like terms: 9 + 1 = 10
10 + 6x + x2 = -1 + 1

Combine like terms: -1 + 1 = 0
10 + 6x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-10' to each side of the equation.
10 + 6x + -10 + x2 = 0 + -10

Reorder the terms:
10 + -10 + 6x + x2 = 0 + -10

Combine like terms: 10 + -10 = 0
0 + 6x + x2 = 0 + -10
6x + x2 = 0 + -10

Combine like terms: 0 + -10 = -10
6x + x2 = -10

The x term is 6x.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6x + 9 + x2 = -10 + 9

Reorder the terms:
9 + 6x + x2 = -10 + 9

Combine like terms: -10 + 9 = -1
9 + 6x + x2 = -1

Factor a perfect square on the left side:
