Exercises Polynomials and factoring

Example 8.19 from Elementary Algebra, 8.2 Multiply and Divide Rational Expressions

Multiply and Divide Rational Expressions: example 8.19

Mulitply: $\frac{2 x}{x^{2} - 7 x + 12} \cdot \frac{x^{2} - 9}{6 x^{2}} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Mulitply: $\frac{5 x}{x^{2} + 5 x + 6} \cdot \frac{x^{2} - 4}{10 x} .$
