factor completely 16b^2-49 Is the binomial factorable if so what is the answer?????

OpenStudy (anonymous):

(4b+7)(4b-7)

OpenStudy (anonymous):

Ok I'm not sure which answer is right, someone else gave me the answer (3b+7)(3b-7)?

OpenStudy (anonymous):

sorry , shouldn't have been a question mark. the square root of 16 is 4

OpenStudy (anonymous):

and the other answer you were given would multiply out to 9b^2 -49

OpenStudy (anonymous):

ok, I was just wondering and making sure. I would have thought it to be the same answer you gave me because I was sitting here trying to figure out how they got the other answer

OpenStudy (anonymous):

Thank you
