This lesson uses a box as a visual aid to reinforce factoring as the inverse of multiplying, combining lessons of factoring out the GCF and factoring four-term quadratic polynomials. All practice problems are quadratic equations split into four terms with an integer GCF (includes both positive and negative GCF). Answer key included.
There are 15 practice problems:
