Can someone me with this it would really ? !

4x^4-4x^3-16x^2+16x

Step-by-step explanation:

To do this problem, you have to multiply the top equation by the bottom. To do this, you would multiply each term of x^2+x-2 by (-8x) and (4x^2). Think of it like the distributive property. We multiply (x^2) with (-8x) and so on. With the -8x term we get (-8x^3-8x^2+16x).

Now you do the same for the term 4x^2 to get (4x^4+4x^3-8x^2).

Then you combine like terms to get 4x^4-4x^3-16x^2+16x.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
