add
(8m^3-3m^2+m-5)+(8m^3+3m^2-4m-2)
Redistribute for like terms.
= (8+8)m3+(-3+3)m2+(1-4)m+(-5-2)
= ...
To add the given expressions, we can combine like terms. Like terms are terms that have the same variable(s) raised to the same power(s).
Let's rearrange the expression by grouping the like terms together:
(8m^3 + 8m^3) + (-3m^2 + 3m^2) + (m - 4m) + (-5 - 2)
Now, simplify each group of like terms:
(16m^3) + (0) + (-3m) + (-7)
Combine like terms:
16m^3 - 3m - 7
Therefore, the sum of the given expressions is 16m^3 - 3m - 7.
