yes

OpenStudy (anonymous):

ok I have on more just want to make sure is right... its 16b^2+8b-35... I got (4b-5)(7+4b) now is that right because I was told it was and then I was told it wasnt

OpenStudy (anonymous):

factoring the trinomial completely...sorry

jimthompson5910 (jim_thompson5910):

that's correct, but you might want to rearrange the terms to get (4b-5)(4b+7)

jimthompson5910 (jim_thompson5910):
