Question

How could I group 12b^2-17b+6 to factor by grouping? I've already tried 12b^2-10b-7b+6 but it doesn't make sense to me...

Answer 1

Try this
\[ 12b^2-17b+6=(12b^2-8b)+(-9b+6) \]

Answer 2

12b^2 - 8b - 9b +6
4b(3b - 2) - 3 (3b -2)

Answer 3

I just figured it out, I was missing the 8 and 9. Thanks for all the help, I appreciate it!
