Solution for (x+3)(x+3)=x*x+ax+9 equation:


Simplifying
(x + 3)(x + 3) = x * x + ax + 9

Reorder the terms:
(3 + x)(x + 3) = x * x + ax + 9

Reorder the terms:
(3 + x)(3 + x) = x * x + ax + 9

Multiply (3 + x) * (3 + x)
(3(3 + x) + x(3 + x)) = x * x + ax + 9
((3 * 3 + x * 3) + x(3 + x)) = x * x + ax + 9
((9 + 3x) + x(3 + x)) = x * x + ax + 9
(9 + 3x + (3 * x + x * x)) = x * x + ax + 9
(9 + 3x + (3x + x2)) = x * x + ax + 9

Combine like terms: 3x + 3x = 6x
(9 + 6x + x2) = x * x + ax + 9

Multiply x * x
9 + 6x + x2 = x2 + ax + 9

Reorder the terms:
9 + 6x + x2 = 9 + ax + x2

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

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

Combine like terms: 9 + -9 = 0
0 + 6x + x2 = 9 + ax + -9 + x2
6x + x2 = 9 + ax + -9 + x2

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

Combine like terms: 9 + -9 = 0
6x + x2 = 0 + ax + x2
6x + x2 = ax + x2

Add '-1x2' to each side of the equation.
6x + x2 + -1x2 = ax + x2 + -1x2

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

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

Solving
6x = ax

Solving for variable 'x'.

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

Add '-1ax' to each side of the equation.
-1ax + 6x = ax + -1ax

Combine like terms: ax + -1ax = 0
-1ax + 6x = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-1a + 6) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-1a + 6)' equal to zero and attempt to solve: Simplifying -1a + 6 = 0 Reorder the terms: 6 + -1a = 0 Solving 6 + -1a = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1a = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1a = 0 + -6 -1a = 0 + -6 Combine like terms: 0 + -6 = -6 -1a = -6 Add 'a' to each side of the equation. -1a + a = -6 + a Combine like terms: -1a + a = 0 0 = -6 + a Simplifying 0 = -6 + a The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
