math exam prep question
posted by Nikki on .
Simplify:
1/4a+2 + 4/6a+3
I got 14/6(2a+1)
but I don't think it is right

1/(4a+2) = 1/2(2a+1)
4/(6a+3) = 4/3(2a+1)
Now you have
1/2(2a+1) + 4/3(2a+1)
Change it all to be over 6(2a+1):
3/6(2a+1) + 8/6(2a+1) = 1/6(2a+1)
How did yo get 14?
forget the (2a+1) for now
1/2 + 4/3 = 3/6 + 8/6 = 11/6 
oops. typo. that is 11/6(2a+1), not "1"

oh yeah sorry for some reason i did 8+6/6(2a+1)...it should have been 11 thanks for the help:)
