Factoring Common Factors Practice Test

Recognize repeated binomial or polynomial factors and factor them using the distributive property.

Factoring Common Factors Practice Test

20 questions on common binomials, polynomial factors, and complete factoring.

About This Factoring Common Factors Practice Test

Recognizing a repeated algebraic expression as one object is an important bridge between basic GCF factoring and grouping.

The test focuses on repeated factors, nested numerical and variable GCFs, differences of squares after a common factor, and deciding whether a factorization is complete.

Skills Covered

You will factor common binomials, squared binomials, and polynomial expressions, then continue with numerical GCFs or special-product identities.

How to Approach the Questions

  1. Mark the entire repeated expression as a temporary single factor.
  2. Factor it exactly as you would factor a common variable.
  3. Combine the terms left outside the common factor.
  4. Inspect both resulting factors for additional factoring.

Common Mistakes to Avoid

Typical mistakes include changing the sign of the repeated factor, combining unlike outside terms, omitting the common binomial, and stopping before a remaining GCF or difference of squares is factored.
