Other Factoring Techniques
The process of factoring binomials and quadratic trinomials is pretty much scripted with the various choices available for each format. When you start factoring expressions with more than three terms, you need different techniques to create the factorization — or to recognize that factors may not even exist.
The Problems You'll Work On
In this chapter on factoring polynomials, you deal with the following situations:
What to Watch Out For
Here are a few things to keep in mind while you work on the factoring:
Factoring by Grouping
536–543 Factor by grouping.
536. bc − 3b + 2c − 6
537. x2 − abx + xyz − abyz
538. 2x3 − 3x2 + 2x − 3
539. 2xz2 + 8x − 3z2 − 12
540. n3/2 + 2n − 4n1/2 − 8
541. y5/2 − 3y2 + 2y1/2 − 6
542. 4x − 12 + xy − 3y − xz + 3z
543. kx + 4x + ky + 4y + kz + 4z
Combining Other Factoring Techniques with Grouping
544–547 Factor each completely, beginning with grouping.
