Please help its my test tomorrow and I am gonna fail. I will give medal too

OpenStudy (anonymous):

what do you need help with?

OpenStudy (anonymous):

28bx12bc

OpenStudy (anonymous):

do you mean 28b times 12bc or just 12bx12bc

OpenStudy (anonymous):

and what are you trying to do? simplify?

OpenStudy (anonymous):

in simple words- 28 times b times 12 times b times c

OpenStudy (anonymous):

ok, are you trying to simplify?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

please tell me answer

OpenStudy (anonymous):

ok. since its only multiplication, you could put the variables/numbers in any order you want. so lets rearrange them so numbers match up with numbers, and any of the same variables match up

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

28 b 12 b c lets make it 28*12 b*b c

OpenStudy (anonymous):

do you get what i did?

OpenStudy (anonymous):

so then its (28*12)(b*b)(c)

OpenStudy (anonymous):

so just replace the answer to 28*12 in the first set of parenthesis, and then replace the second set of parenthesis with the simplified version of b*b
