Solution for X*(9-X)*(9-X)=100 equation: 


Simplifying
X(9 + -1X)(9 + -1X) = 100

Multiply (9 + -1X) * (9 + -1X)
X(9(9 + -1X) + -1X * (9 + -1X)) = 100
X((9 * 9 + -1X * 9) + -1X * (9 + -1X)) = 100
X((81 + -9X) + -1X * (9 + -1X)) = 100
X(81 + -9X + (9 * -1X + -1X * -1X)) = 100
X(81 + -9X + (-9X + 1X2)) = 100

Combine like terms: -9X + -9X = -18X
X(81 + -18X + 1X2) = 100
(81 * X + -18X * X + 1X2 * X) = 100
