Work Step by Step

To combine like terms, you add/subtract the coefficients. When a variable term has no coefficient, the implied coefficient is 1. $-ab^2-ab^2\longrightarrow$ write the coefficient =$-1ab^2-1ab^2\longrightarrow$ use the distributive property to factor out the coefficients =$(-1-1)(ab^2)\longrightarrow$ subtract =$-2ab^2$
