Question

What is the difference of the polynomials? (8r6 s3 - 9r5 s4 + 3r4 s5) - (2r4 s5 - 5r3s6 - 4r5 s4)

Answer 1

`8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6`

Explanation:

Step 1: Distribute the negative

`8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4s^5s^4`

Step 2: Combine like terms

When you do so, you should get your answer.
