Homework Help: math

Posted by y912f on Saturday, October 9, 2010 at 11:54am.

How can I factor this:
2a^2 + 19a +42
?
I've been trying to do this for so long but I can't figure it out.
Please explain the answer as well.
The only way I can come up with is trial and error, and I've been trying so long and nothing fits..?

figured it out:
(2a+7)(a+6)
Just needed to switch the order around : )
