9/8x²+2x-15 - 5/2x³+3x + 4/4x²-5x​

Step-by-step explanation:

First combine like terms so for numbers with x^3 you have one:

-

Then x^ 2

(4/4x^2 is just x^2 because 4/4 is 1)

So

Then all numbers with x cancel out because

2x+3x-5x is 0.

Then you just have -15.

So put them back together to get what I wrote in the answer.

Hope that helps lmk if I calculated that wrong!
