-2(x+1)9x=54

Solution for -2(x+1)9x=54 equation:

Simplifying
-2(x + 1) * 9x = 54

Reorder the terms:
-2(1 + x) * 9x = 54

Reorder the terms for easier multiplication:
-2 * 9x(1 + x) = 54

Multiply -2 * 9
-18x(1 + x) = 54
(1 * -18x + x * -18x) = 54
(-18x + -18x2) = 54

Solving
-18x + -18x2 = 54

Solving for variable 'x'.

Reorder the terms:
-54 + -18x + -18x2 = 54 + -54

Combine like terms: 54 + -54 = 0
-54 + -18x + -18x2 = 0

Factor out the Greatest Common Factor (GCF), '-18'.
-18(3 + x + x2) = 0

Ignore the factor -18.
Subproblem 1
Set the factor '(3 + x + x2)' equal to zero and attempt to solve:

Simplifying
3 + x + x2 = 0

Solving
3 + x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + x + -3 + x2 = 0 + -3

Reorder the terms:
3 + -3 + x + x2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + x + x2 = 0 + -3
x + x2 = 0 + -3

Combine like terms: 0 + -3 = -3
x + x2 = -3

The x term is x.  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.
x + 0.25 + x2 = -3 + 0.25

Reorder the terms:
0.25 + x + x2 = -3 + 0.25

Combine like terms: -3 + 0.25 = -2.75
0.25 + x + x2 = -2.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -2.75

Can't calculate square root of the right side.
