Simplify: 5a^2b+7ab+4ab^2 _____________________= ab 2ab+6-4b 5a+7+4b 5ab+7-4b None of the above

can you break down how you got that answer?

OpenStudy (anonymous):

the answer is 5a+7+4b

OpenStudy (anonymous):

the method: take each individual term and divide through by ab, for example 5ba^2 which cancels one of each of the as and bs so 5ba^2 becomes 5a (5 times no bs and 1 a having previously been 5 times 1 b and 2 as)
