Simplify and Identify any x-values ->

I need help simpifying and identifying x-values for this

2x^2+5x^3 / x

If anyone will help they will get *Best Answer :) Thank

(2x²+5x³)/x -->factor the numerator

x²(2+5x)/x

x(2+5x)

because all terms in the numerator contain some form of the denominator (i.e. there is an x in both top and bottom of fraction) we can divide each term by the denominator:
(2x^2 / x) + (5x^3 / x)
which gives the following result:
2x + 5x^2
there is no way to identify x values because this expression is not equal to anything

The way you wrote down the problem here, could be seen in two different ways...

One way:
(2x^2) + (5x^3 / x)

Second way:
(2x^2 + 5x^3) / x

---------------------------------------…

For the first way:

(2x^2) + (5x^3 / x)

1.) Divide the x from the 5x^3.
This is simple. You basically just subtract 1x from the 5x^3 and you would end up with 5x^2.

2.) Re-write:

2x^2 + 5x^2

3.) Now just add them both together :)

Answer: 7x^2

---------------------------------------…

For the second way:

(2x^2 + 5x^3) / x

1.) All you can do is put the x under both numbers:

(2x^2 / x) + (5x^3 / x)

2.) Next you would divide the x from both 2x^2 and 5x^3.

You would end up with:

2x + 5x^2

3.) The above would be your answer....but you could also factor:

x(2 + 5x)

There's not much more to do... :P
Chances are that your problem was the first way I explained :)

(2x^2+5x^3)/x
2x+5x^2
x(5x+2)

x=0

5x+2=0
5x= -2
x=(-2/5)
