(-2k^3-7k^2+5k)+(6k^2+3k)

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡Ф

= −2k^3 − k^2 + 8k

Step-by-step explanation:

Let's simplify step-by-step.

−2k^3 − 7k^2 + 5^k + 6k^2 + 3^k

= − 2k^3 + −7k^2 + 5k + 6k^2 + 3^k

Combine Like Terms:

= − 2k^3 + −7k^2 + 5^k + 6k^2 + 3^k

= ( −2k^3 ) + (−7k^2 + 6k^2 ) + (5^k + 3^k)

= −2k^3 + −k^2 + 8k
