Solution:

Detailed explanation:

Hii! Let's factorise this expression!

Did you see that both terms, x^3 and 2x, have an x in common? That's what we are going to factor out, by dividing x^3 and 2x by x.

x^2+2 is what we obtain.

Now, this can't be the end of the process. We also need to put parentheses around x^2+2.

(x^2+2)

Next we put that x we factored out a short while ago outside the parentheses.

x(x^2+2). Did you get it?

Answer:


x(x^2+2)

Explanation:

Since x is the only common term, you factor that part out using the distributive property.
