Factoring Strategies for Polynomials

6.7.1 Factoring Strategies for Polynomials

6.7.1 • Factoring Strategies for Polynomials

Warm Up

1.

Working with a partner, list as many strategies as you can for factoring polynomials.

Your answers may vary, but here are some examples:

  • Factoring by finding the GCF of an expression and using reverse distribution
  • Factoring using grouping
  • Factoring trinomials of the form x2+bx+cx2+bx+c (undo FOIL)
  • Factoring trinomials of the form ax2+bx+cax2+bx+c using trial and error
  • Factoring trinomials using the “acac” method
  • Factoring using substitution
  • Factoring the difference of squares
  • Factoring perfect square trinomials
2.

Work with your partner to write a sample polynomial that would be fitting for each strategy listed.
