To add the expressions −3k+4k^3−2 and 9k^2−3k^3+4k−3, we combine like terms.
First, let's combine all the terms with k^3: -3k^3 + 4k^3 = k^3.
Next, let's combine all the terms with k^2: 0k^2 + 9k^2 = 9k^2.
Now, let's combine all the terms with k: -3k + 4k = k.
Finally, let's combine the constants: -2 + (-3) = -5.
Putting it all together, we have the simplified expression:
k^3 + 9k^2 + k - 5.
Add the expressions.
