Question

2c+6/4-c*4c-16/5c+15=

Answer 1

Is this the expression?

\(\Large 2c+\dfrac{6}{4}-c\cdot4c-\dfrac{16}{5c}+15=\)

Because that's what you have written above.

But I suspect what you MEAN is:

\(\Large \dfrac{2c+6}{4-c}\cdot\dfrac{4c-16}{5c+15}=\)

Which, if you don't want to use the equation editor, you can convey clearly with just a few well-placed parentheses:
(2c+6)/(4-c)*(4c-16)/(5c+15)=

Answer 2

yeah its the second one

Answer 3

Assuming this:

\(\Large \dfrac{2c+6}{4-c}\cdot\dfrac{4c-16}{5c+15}=\)

Factor what you can (both num'rs, and the 2nd den'r, have GCF's that you can pull out).

See what's left - something may cancel.

Answer 4

Reduce fully first, then see what you have left.

Answer 5

That is, factor each of:

2c+6
4c-16
5c+15

See what you have that might cancel.
