Solution for (n-7)*(n-7)*(n-7)= equation: 


Simplifying
(n + -7)(n + -7)(n + -7) = 0

Reorder the terms:
(-7 + n)(n + -7)(n + -7) = 0

Reorder the terms:
(-7 + n)(-7 + n)(n + -7) = 0

Reorder the terms:
(-7 + n)(-7 + n)(-7 + n) = 0

Multiply (-7 + n) * (-7 + n)
(-7(-7 + n) + n(-7 + n))(-7 + n) = 0
((-7 * -7 + n * -7) + n(-7 + n))(-7 + n) = 0
((49 + -7n) + n(-7 + n))(-7 + n) = 0
(49 + -7n + (-7 * n + n * n))(-7 + n) = 0
(49 + -7n + (-7n + n2))(-7 + n) = 0

Combine like terms: -7n + -7n = -14n
(49 + -14n + n2)(-7 + n) = 0

Multiply (49 + -14n + n2) * (-7 + n)
(49(-7 + n) + -14n * (-7 + n) + n2(-7 + n)) = 0
((-7 * 49 + n * 49) + -14n * (-7 + n) + n2(-7 + n)) = 0
((-343 + 49n) + -14n * (-7 + n) + n2(-7 + n)) = 0
(-343 + 49n + (-7 * -14n + n * -14n) + n2(-7 + n)) = 0
(-343 + 49n + (98n + -14n2) + n2(-7 + n)) = 0
(-343 + 49n + 98n + -14n2 + (-7 * n2 + n * n2)) = 0
(-343 + 49n + 98n + -14n2 + (-7n2 + n3)) = 0

Combine like terms: 49n + 98n = 147n
(-343 + 147n + -14n2 + -7n2 + n3) = 0

Combine like terms: -14n2 + -7n2 = -21n2
(-343 + 147n + -21n2 + n3) = 0

Solving
-343 + 147n + -21n2 + n3 = 0

Solving for variable 'n'.
