Solution for (x-3)(x-3)=6(x-3) equation:


Simplifying
(x + -3)(x + -3) = 6(x + -3)

Reorder the terms:
(-3 + x)(x + -3) = 6(x + -3)

Reorder the terms:
(-3 + x)(-3 + x) = 6(x + -3)

Multiply (-3 + x) * (-3 + x)
(-3(-3 + x) + x(-3 + x)) = 6(x + -3)
((-3 * -3 + x * -3) + x(-3 + x)) = 6(x + -3)
((9 + -3x) + x(-3 + x)) = 6(x + -3)
(9 + -3x + (-3 * x + x * x)) = 6(x + -3)
(9 + -3x + (-3x + x2)) = 6(x + -3)

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

Reorder the terms:
9 + -6x + x2 = 6(-3 + x)
9 + -6x + x2 = (-3 * 6 + x * 6)
9 + -6x + x2 = (-18 + 6x)

Solving
9 + -6x + x2 = -18 + 6x

Solving for variable 'x'.

Reorder the terms:
9 + 18 + -6x + -6x + x2 = -18 + 6x + 18 + -6x

Combine like terms: 9 + 18 = 27
27 + -6x + -6x + x2 = -18 + 6x + 18 + -6x

Combine like terms: -6x + -6x = -12x
27 + -12x + x2 = -18 + 6x + 18 + -6x

Reorder the terms:
27 + -12x + x2 = -18 + 18 + 6x + -6x

Combine like terms: -18 + 18 = 0
27 + -12x + x2 = 0 + 6x + -6x
27 + -12x + x2 = 6x + -6x

Combine like terms: 6x + -6x = 0
27 + -12x + x2 = 0

Factor a trinomial.

Subproblem 1

Set the factor '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Divide each side by '-1'. x = 3 Simplifying x = 3

Subproblem 2

Set the factor '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Divide each side by '-1'. x = 9 Simplifying x = 9

Solution

x = {3, 9}
