Question

4q-2q+1

Answer 1

So 4-2=2
so the anser is 2q+1

you can only add LIKE TERMS meaning you can only add y terms with y terms, y^2 terms with y^2 and number with numbers
just add up how many there are and find the answer

Answer 2

This is deceptively simple: there are only three terms, one is a constant (1) and two are coefficients of q (4q, -2q). To simplify the like terms, just simplify the terms containing q.
