Factor Did you get?
Wolfram Alpha says it is OK.
Weird, Wonderful but Ugly. So, a road not taken. Find linear factors.
Factor into Linear Factors Did you get?
This is the “best” linear factorization! Why? Most Useful Easiest to Find
Most useful when • Solving equations • Understanding quadratic functions • Simplifying rational expressions • Finding partial fractions
Solving equations
Understanding quadratic functions
simplifying rational expressions
Finding partial fractions with traditional factoring
Finding partial fractions with ‘new” factoring
Easiest to find. First, review factoring trinomials whose leading Coefficient is I. Find two factors of ______ that add to _____. They are ____ and _____.
So, fairly easy - may need to be systematic. Now review factoring trinomials whose leading Coefficient is not I.
More review factoring trinomials whose leading Coefficient is not I. Find two factors of ______ that add to _____. They are ____ and _____.
Now the easy way. Find two factors of ______ that add to _____. They are ____ and _____.
Why it works.
Why the method works in general. Consider, Find two factors of ______ that add to _______. They are ____ and _____.

Effectively stretching the Xaxis.
So, try it you will like it. And help me lead the Revolution!
