Question

Which expression is equivalent to (3m2 + 5m - 2) + (-2m + 18)

Answer 1

The given expression is

`(3m^2+5m-2)+(-2m+18)`

First, reduce like terms, 5m and -2m are like terms, -2 and 18 are like terms. Since they have different signs, we subtract them. Therefore, the given expression is equivalent to

`3m^2+3m+16`
