Question

9/8x²+2x-15 - 5/2x³+3x + 4/4x²-5x​

Answer 1

Answer:

$-\frac{5}{2} x^{3} +\frac{17}{8} x^{2} -15$

Step-by-step explanation:

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

-$\frac{5}{2} x^{3}$

Then x^ 2

$\frac{9}{8}x^{2} +x^{2}$

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

So

$\frac{17}{8} x^{2}$

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!
