okay guys Im stuck and i don't know what to do after this step.
here is the problem:
12b^2-29b+15
me:
3(b^2+20b)(9b+5)
It has to be factored out by grouping why do I feel it is not complete?

$$12b^2-29b+15$$$$(4b-3)(3b-5)$$This is what you should have done. I'm not sure how you got your answer. This one shouldn't be factored by grouping as it only has 3 terms.

If you'll notice, if you re-simplify your answer, you won't get the original expression. This is one way to check yourself.
