Answer:

2x^8-6x^7+11x^6-2x+10

Step-by-step explanation:

To find: 10x^8+11x^6-2x+5-(8x^8+6x^7-5)

Solution:

Like terms refer to terms with same variables and same powers.

Two like terms can be added or subtracted.

Consider the following expression:

10x^8+11x^6-2x+5-(8x^8+6x^7-5)=10x^8+11x^6-2x+5-8x^8-6x^7+5\\=(10-8)x^8-6x^7+11x^6-2x+(5+5)\\=2x^8-6x^7+11x^6-2x+10

(Here, like terms are added or subtracted)
