  1. Math 20-1 Chapter 6 Rational Expressions and Equations Teacher Notes 6.2 Multiply and Divide Rational Expressions

  2. 6.2 Multiply Rational Expressions • To Multiply Rational Expressions • Factor the polynomials in each numerator and denominator. • Given that if are two rational • expressions, then • Divide out common factors in the numerator and • denominator. Leave the remaining factors in factored form. When you multiply rational expressions, follow procedures similar to those for multiplying rational numbers. 6.2.1

  3. Multiply Rational Expressions Multiply: Factor the numerator and denominator. Divide out the common factors. 6.2.2

  4. Multiply Rational Expressions Multiply: Factor each numerator and denominator. List non-permissible values. x = –4, x = 7, x = –1 Divide out common factors. Avoiding Mistakes: The domain of a rational expression is always determined before simplifying the expression. 6.2.3

  5. Multiply Rational Expressions Your Turn Multiply and write the answer in simplest form NPVs: x = -4, x = -5, x = -6 6.2.4

  6. Divide Rational Expressions Multiply the dividend by the reciprocal of the divisor. Example 6.2.5

  7. Divide Rational Expressions Determine the quotient in simplest form Multiply by the reciprocal Factor the numerator and denominator. State NPVs Divide out common factors. 6.2.6

  8. Multiply and Divide Rational Expressions Simplify Multiply by the reciprocal Factor the numerator and denominator. State NPVs Divide out common factors. 6.2.7
