Summary of factoring techniques
Here are the steps for factoring polynomials in Intermediate Algebra:
These techniques will work
for all polynomials up to degree 2 and for some polynomials of higher degree.
- If necessary, put the polynomial in standard form.
- If possible, pull out any factors common to all terms (§6.1).
- If there are four terms, try factoring by grouping (§6.1).
- If there are three terms,
try factoring into two binomials (§§6.2&6.3)
or factoring as a perfect square (§6.4).
- If there are two terms (or if you now have factors with two terms),
try factoring as a sum or difference of squares or cubes (§6.4).
- Keep factoring the factors until you can factor no further
