Solution for =(x-3)(x^2+3x+9) equation:


Simplifying
0 = (x + -3)(x2 + 3x + 9)

Reorder the terms:
0 = (-3 + x)(x2 + 3x + 9)

Reorder the terms:
0 = (-3 + x)(9 + 3x + x2)

Multiply (-3 + x) * (9 + 3x + x2)
0 = (-3(9 + 3x + x2) + x(9 + 3x + x2))
0 = ((9 * -3 + 3x * -3 + x2 * -3) + x(9 + 3x + x2))
0 = ((-27 + -9x + -3x2) + x(9 + 3x + x2))
0 = (-27 + -9x + -3x2 + (9 * x + 3x * x + x2 * x))
0 = (-27 + -9x + -3x2 + (9x + 3x2 + x3))

Reorder the terms:
0 = (-27 + -9x + 9x + -3x2 + 3x2 + x3)

Combine like terms: -9x + 9x = 0
0 = (-27 + 0 + -3x2 + 3x2 + x3)
0 = (-27 + -3x2 + 3x2 + x3)

Combine like terms: -3x2 + 3x2 = 0
