Answer:

1.x⁴+2x³-4x²-5x+5 / x+2

2.x⁴-5x³+10x²-3x-2 / x-1

Step-by-step explanation:

The givens has no same variables so its answer will be the same.Because we can only add and divide variables with the same variables

For example:

5x+2 = 5x+2 ---- this is already the answer because there's no same variables therefore we can't add it

5x+2x = 7x ------Here we have the same variable which is x so we can add it

5x³+2x = 5x³+2x-----In this given example,we can see that they were same variable however the other variable is raised to 3 so we can't add it
