Question

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

Thank you
