Definitions:

Difference Of Cubes

A formula expressing the subtraction of two cubed numbers as a product of a binomial and a trinomial, specifically a^3 - b^3 = (a - b)(a^2 + ab + b^2).

Trinomial

A polynomial with three terms, typically of the form ax^2 + bx + c.

Difference Of Two Squares

A mathematical expression of the form \(a^2 - b^2\), which can be factored into \((a + b)(a - b)\).
