The key is to “memorize” or remember the patterns involved in the formulas. Case 1: The polynomial in the form a 3 + b 3 {a^3} + {b^3} a3+b3 is called the sum of two cubes because two cubic terms are being added together
The Difference of Two Cubes is a special case of multiplying polynomials : (a−b)(a2+ab+b2) = a3 − b3. It comes up sometimes when solving things, so is worth remembering.
