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


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

Reorder the terms:
3(-6 + z) = (z + -6)(z + -6)
(-6 * 3 + z * 3) = (z + -6)(z + -6)
(-18 + 3z) = (z + -6)(z + -6)

Reorder the terms:
-18 + 3z = (-6 + z)(z + -6)

Reorder the terms:
-18 + 3z = (-6 + z)(-6 + z)

Multiply (-6 + z) * (-6 + z)
-18 + 3z = (-6(-6 + z) + z(-6 + z))
-18 + 3z = ((-6 * -6 + z * -6) + z(-6 + z))
-18 + 3z = ((36 + -6z) + z(-6 + z))
-18 + 3z = (36 + -6z + (-6 * z + z * z))
-18 + 3z = (36 + -6z + (-6z + z2))

Combine like terms: -6z + -6z = -12z
-18 + 3z = (36 + -12z + z2)

Solving
-18 + 3z = 36 + -12z + z2

Solving for variable 'z'.

Reorder the terms:
-18 + -36 + 3z + 12z + -1z2 = 36 + -12z + z2 + -36 + 12z + -1z2

Combine like terms: -18 + -36 = -54
-54 + 3z + 12z + -1z2 = 36 + -12z + z2 + -36 + 12z + -1z2

Combine like terms: 3z + 12z = 15z
-54 + 15z + -1z2 = 36 + -12z + z2 + -36 + 12z + -1z2

Reorder the terms:
-54 + 15z + -1z2 = 36 + -36 + -12z + 12z + z2 + -1z2

Combine like terms: 36 + -36 = 0
-54 + 15z + -1z2 = 0 + -12z + 12z + z2 + -1z2
-54 + 15z + -1z2 = -12z + 12z + z2 + -1z2

Combine like terms: -12z + 12z = 0
-54 + 15z + -1z2 = 0 + z2 + -1z2
-54 + 15z + -1z2 = z2 + -1z2

Combine like terms: z2 + -1z2 = 0
-54 + 15z + -1z2 = 0

Subproblem 1

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

Subproblem 2

Set the factor '(6 + -1z)' equal to zero and attempt to solve: Simplifying 6 + -1z = 0 Solving 6 + -1z = 0 Move all terms containing z to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1z = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1z = 0 + -6 -1z = 0 + -6 Combine like terms: 0 + -6 = -6 -1z = -6 Divide each side by '-1'. z = 6 Simplifying z = 6

Solution

z = {9, 6}
