Question

Simplify and find the excluded values of the rational expression... MEDAL!

Answer 1

\[\large \frac{6}{4n} - \frac{3}{15n^2 + 12n}\]

Answer 2

Do you think that I can simply both of the fractions?

Answer 3

n \(\neq\) 0

Answer 4

Rip my english. You could go for a common denominator. First simplify as much as you can though.

Answer 5

And yes very good.

Answer 6

OK.

Answer 7

@sweetburger

Answer 8

Make a common denominator

Answer 9

you can simplify the fractions first and then common denominator \[ \frac{ 6 }{ 4n }=\frac{3}{2n}\] same with other fraction

Answer 10

i got:
\[\frac{3}{2n} - \frac{1}{5n^3 + 4n}\]

Answer 11

Do you understand what a common denominator is?

Answer 12

do you mean 5n^2 ?

Answer 13

oh yes! that's where i have been making my mistake!

Answer 14

now you can find the common denominator
2nd) set it equal to 0

Answer 15

i got my answer:
\(\large \frac{5(3n+2)}{2n(5n+4)}\)

Answer 16

what is the common denominator ??

Answer 17

2n(5n^2 + 4n)

Answer 18

I actually got the answer. It matches with the answer key. thanks for ur help :)

Answer 19

nice. that looks good
you need *excluded values* the value that makes the denominator equal to 0
so just set the denominator equal to 0

Answer 20

np :)
