simplify each polynomial 6g+8k-9g+2k

Combining like terms, we get:

(6g - 9g) + (8k + 2k)

Simplifying:

-3g + 10k

To simplify the given polynomial, we combine the like terms:

The terms that contain 'g' are 6g and -9g.
When we combine these terms, we have 6g - 9g = -3g.

The terms that contain 'k' are 8k and 2k.
When we combine these terms, we have 8k + 2k = 10k.

Finally, putting it all together, the simplified polynomial is:

-3g + 10k.
