Which polynomials would be factored by Grouping?

Check all that apply.

• 8x² + 10x

• 8x² + 10x - 21

• x² - 11x - 12

• 5x³ - 30x² - 6x + 36

Answer explanation

Throughout our lessons you should have been taking note of when to do which type of factoring.

**GCF: any terms as long as they have a common factor other than 1.
**Grouping: only when you have 4 terms.
** Product/Sum or Slide & Divide (both similar methods): only for trinomials.
