Factor:
b%5E2-ab-6a%5E2
The factors of b^2 are (b)(b)
Tha factors of -6a^2 are (-a)(6a) or (2a)(-3a) or the same factors with their signs switched.
Now, how to get the coefficient of the middle term (-1) of your expression from this set of factors. The obvious choice is: (2)+(-3)
The factors are:
b%5E2-ab-6a%5E2+=+%28b%2B2a%29%28b-3a%29
