Solution for =(x^2-18x+81)(x+9) equation: 


Simplifying
0 = (x2 + -18x + 81)(x + 9)

Reorder the terms:
0 = (81 + -18x + x2)(x + 9)

Reorder the terms:
0 = (81 + -18x + x2)(9 + x)

Multiply (81 + -18x + x2) * (9 + x)
0 = (81(9 + x) + -18x * (9 + x) + x2(9 + x))
0 = ((9 * 81 + x * 81) + -18x * (9 + x) + x2(9 + x))
0 = ((729 + 81x) + -18x * (9 + x) + x2(9 + x))
0 = (729 + 81x + (9 * -18x + x * -18x) + x2(9 + x))
0 = (729 + 81x + (-162x + -18x2) + x2(9 + x))
0 = (729 + 81x + -162x + -18x2 + (9 * x2 + x * x2))
0 = (729 + 81x + -162x + -18x2 + (9x2 + x3))

Combine like terms: 81x + -162x = -81x
0 = (729 + -81x + -18x2 + 9x2 + x3)

Combine like terms: -18x2 + 9x2 = -9x2
0 = (729 + -81x + -9x2 + x3)
