Identify the GCF of 12a4b3 + 8a3b2. (4 points) 4a3b2 2a3b 4a2b 8a3b2 I think it's 4a^2b

OpenStudy (igreen):

No, that's incorrect.

OpenStudy (igreen):

\(a^4\) and \(a^3\) \(b^3\) and \(b^2\) Can you find the GCF's of these?

OpenStudy (anonymous):

they're both 1 ... I think

OpenStudy (anonymous):

wait. thats wrong

OpenStudy (anonymous):

GCF of 12 and 8 is .....4 GCF of a^4 and a^3 is.....a^3 {choose smallest exponents with variables} GCF of b^3 and b^2 is.....b^2 GCF = 4a³b²

OpenStudy (anonymous):

4a^3b^2

OpenStudy (anonymous):

what you did was kinda like cancel them out
