If g(x) = 9 – 3x2, then g (–1) = 303. If , then h(–4) = , then w(4) = 39 40 Part I: The Questions Chapter 7 Multiplying by One or More Terms M ultiplying algebraic expressions is much like multiplying numbers, but the introduction of variables makes the process just a bit more interesting. Products involving variables call on the rules of exponents. And, because of the commutative property of addition and multiplication, arrangements and rearrangements of terms and factors can make the process simpler.
