Express each fraction with the lcd as the. It's going to be negative z to the third times z plus six. Write each rational expression by whatever it takes so that it will the lcd by using the fundamental principle of rational expressions, namely.
If We Review The Procedure We Used With Numerical Fractions, We Will Know What To Do With Rational Expressions.
Since i have monomials in the denominators, the lcd can be obtained by simply taking the least common multiple of the coefficients, where lcm (3, 6) = 6, and multiply that to the variable x with the highest exponent.the lcd should be (lcm of. Calculations can be performed easily on the numerator as the denominators are equal. Express the answer as a simplified rational expression, and state the domain.
