DIVIDING RATIONAL EXPRESSIONS When dividing rational expressions we change the division problem into an equivalent multiplication problem Multiply the first expression by the reciprocal of the divisor In other words keep the first expression change the operation from division to multiplication and “flip” the second expression
Examples, videos, worksheets, solutions, and activities to help Algebra students learn how to multiply and divide rational expressions. How to multiply rational expressions? 1. Completely factor the expressions in the numerator and denominator 2. Reduce the fractions by canceling any similar factors that are in the numerator and denominator 3.
A rational expression is considered simplified if there are no common factors in its numerator and denominator. We use the Equivalent Fractions Property to simplify numerical fractions. We restate it here as we will also use it to simplify rational expressions.
Typically, rational expressions will not be given in factored form. In this case, first factor all numerators and denominators completely. Next, multiply and cancel any common factors, if there are any. Factor the denominator x2 ? 25 as a difference of squares. Then multiply and cancel.
