Solution for a^3-b^3=(a-b)(a^2+ab+b^2) equation:


Simplifying
a3 + -1b3 = (a + -1b)(a2 + ab + b2)

Reorder the terms:
a3 + -1b3 = (a + -1b)(ab + a2 + b2)

Multiply (a + -1b) * (ab + a2 + b2)
a3 + -1b3 = (a(ab + a2 + b2) + -1b * (ab + a2 + b2))
a3 + -1b3 = ((ab * a + a2 * a + b2 * a) + -1b * (ab + a2 + b2))

Reorder the terms:
a3 + -1b3 = ((ab2 + a2b + a3) + -1b * (ab + a2 + b2))
a3 + -1b3 = ((ab2 + a2b + a3) + -1b * (ab + a2 + b2))
a3 + -1b3 = (ab2 + a2b + a3 + (ab * -1b + a2 * -1b + b2 * -1b))
a3 + -1b3 = (ab2 + a2b + a3 + (-1ab2 + -1a2b + -1b3))

Reorder the terms:
a3 + -1b3 = (ab2 + -1ab2 + a2b + -1a2b + a3 + -1b3)

Combine like terms: ab2 + -1ab2 = 0
a3 + -1b3 = (0 + a2b + -1a2b + a3 + -1b3)
a3 + -1b3 = (a2b + -1a2b + a3 + -1b3)

Combine like terms: a2b + -1a2b = 0
a3 + -1b3 = (0 + a3 + -1b3)
a3 + -1b3 = (a3 + -1b3)

Add '-1a3' to each side of the equation.
a3 + -1a3 + -1b3 = a3 + -1a3 + -1b3

Combine like terms: a3 + -1a3 = 0
0 + -1b3 = a3 + -1a3 + -1b3
-1b3 = a3 + -1a3 + -1b3

Combine like terms: a3 + -1a3 = 0
-1b3 = 0 + -1b3
-1b3 = -1b3

Add 'b3' to each side of the equation.
-1b3 + b3 = -1b3 + b3

Combine like terms: -1b3 + b3 = 0
0 = -1b3 + b3

Combine like terms: -1b3 + b3 = 0
0 = 0
