Multiplying a monomial by a polynomial

We use the distributive property: k(a+b)=ka+kbk(a+b)=ka+kb. Multiply the monomial by every term of the polynomial, then combine like terms.
The factor must multiply each term inside the parentheses
Watch the signs when you multiply
At the end, combine like terms
Warm-up: practice multiplying monomials.
