24x^5-15x^4/3x^2

• Math 221 -

Be careful with numerators and denominators and parentheses

What you wrote is

24x^5- (15x^4/3x^2)

but I bet what you mean is

(24x^5-15x^4)/3x^2

which is

24x^5/3x^2 - 15x^4/3x^2

or
8 x^3 - 5 x^2

• Math 221 -

No the one I wrote is correct you divide by 3x^2 and there was no parentheses

• Math 221 -

ok if you really mean that.
I had a hunch it looked like

24x^5-15x^4
------------
3x^2

but if you really mean
24 x^5 - (15 x^4/3 x^2)
then

24 x^5 - 5 x^2

• Math 221 -

It looks like the first one

• Math 221 -

Go with my original reply then. I had a hunch that was the case because both 24 and 15 were divisible by 3.

• Math 221 -

when you have more than one term in a numerator or denominator, put a parenthesis around them

a + b/c is just that , a alone plus b/c
but
(a+b) / c
is
a+b
-----
c
or
a/c + b/c
