Expression 1 + Expression 2:
(-3k + 4k^3 - 2) + (9k^2 - 3k^3 + 4k - 3) = (-3k + 4k^3 - 2 + 9k^2 - 3k^3 + 4k - 3)
Combine like terms:
-3k + 4k^3 + 9k^2 - 3k^3 + 4k - 2 - 3
= 4k^3 - 3k^3 + 9k^2 - 3k + 4k - 3k - 2 - 3
= (4k^3 - 3k^3) + 9k^2 + (4k - 3k) + (-2 - 3)
Simplify:
k^3 + 9k^2 + k - 5
(-3k + 4k^3 - 2) + (9k^2 - 3k^3 + 4k - 3) = (-3k + 4k^3 - 2 + 9k^2 - 3k^3 + 4k - 3)
Combine like terms:
-3k + 4k^3 + 9k^2 - 3k^3 + 4k - 2 - 3
= 4k^3 - 3k^3 + 9k^2 - 3k + 4k - 3k - 2 - 3
= (4k^3 - 3k^3) + 9k^2 + (4k - 3k) + (-2 - 3)
Simplify:
k^3 + 9k^2 + k - 5
