Common-factor extraction

Factoring out a common factor means using the distributive law backwards: the chosen factor must divide every term.

Prerequisites: Polynomials and monomial division

Goal: Extract a common factor and verify factorization using the distributive law.

What you need to know before the exercises

In this lesson: Extract a common factor and verify factorization using the distributive law.

New concept: Factoring out a common factor means rewriting a sum as a product: extract the factor present in every term, leaving inside the parentheses exactly what reconstructs the original expression by distribution.

How to proceed: For the number use the GCD of the coefficients; for each variable use the smallest exponent present in every term.

You can already assume: Polynomials and monomial division.
