factoring cubes

Let us learn about factoring cubes

The other 2 special factoring formulas are 2 sides of the same coin: the sum & difference of cubes. These are the formulas used.

a³ + b³ = (a + b)(a² – ab + b2)

a³ – b³ = (a – b)(a² + ab + b2)

The rule for factoring the sum of 2 perfect cubes is almost the same as the rule for factoring the difference between perfect cubes. To change 2 little signs to make it work. The sum of 2 cubes equal to the sum of its roots times the squares of its roots minus the product of the roots that looks like

a³ +b³ = (a+b) (a² –ab +b²)
