Multiplication Involving Rational Expressions
Multiplication involving rational expressions works the same way as multiplication of any other fractions. We
multiply the numerators to find the numerator of the product, and then multiply the denominators to find the
denominator of the product. Before multiplying, it is helpful to factor the numerators and denominators just as we
did when simplifying rational expressions. After multiplying we are often able to simplify the rational expression
2x2+6x
9 9x
and simplify
Example 5 Multiply the rational expressions: 9.
х2 — 2х- 3
x26x+9
9(2x) (-9)(x-1)
(x -3)(x+)(x* 3)
9 (x-1)
(x+3)
ax
(x-3)(x+1)
= - 102x (x-)
(x-3)(x41)(x+3)
