Question

simplify ( c^2 - 4cd / 3a ) ( 18a^2 b / c-4d ) how u simplify? can u show steps of canceling too pls? thank you

Answer 1

multiply everything out.

its fractions so you can multiply across

Answer 2

No, no....cancel first.

Answer 3

just a wonder estudier but how can you cancel with no common factors in the two separate fractions

Answer 4

For a start, I have 18a^2b in the top and 3a in the bottom.

And a (c-4d) in top and bottom.

Answer 5

It's just multiplication (and the way he has typed it).

U can just start cancelling right away.

Answer 6

thats why i said multiply first lol...

Answer 7

No need.

Answer 8

\[(c^2 - 4cd)18a^2b/3a(c-4d)\]

Answer 9

well no matter what you do it comes out to 6abc

Answer 10

Explain it as he asked...

Answer 11

U never know, u might get another medal...:-)

Answer 12

i canceled and got 6abc^2 the two c's are from c^2 - 4cd

Answer 13

c^2 -4 cd = c(c-4d) and you can cancel the c-4d top and bottom along with the a top and bottom and then 3/18 = 1/6.

Answer 14

I have no time for people who post answers without an explanation...

Answer 15

well i'll use estudier's way cause you gave me a medal :D

using the equation he gave above you get
18a^2bc^2 - 72 a^2bcd
----------------------
3ac- 12ad

take out 3a your left with

6abc^2 - 24abcd
---------------
c-4d

take out the c-4d and your left with 6abc
