Practice: Factoring out the GCF and factoring by grouping
Factoring practice problems with solutions: factoring out the GCF, a common binomial factor, factoring by grouping with sign changes, and mental math with the distributive property.
Review the lessonWork each problem out on paper before you open the solution. If your answer is off, compare the steps and find where you went wrong. If a problem stops you cold, go back to the lesson: every set links to it.

Practice 8Quick check
How do you factor \(7x^2 - 14x\)?
The GCF is \(7x\); dividing leaves \(x\) and \(-2\).
Practice 9Quick check
How do you factor \(-4y - 12\)?
Factoring out \(-4\) flips both signs: \(-4 \cdot y\) and \(-4 \cdot 3\).
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
