Which of the following is the quotient of the rational expressions shown below?
Understanding Rational Expressions and Division
Rational expressions are fractions that contain variables and/or numbers in the numerator and/or denominator. When we divide one rational expression by another, we are essentially multiplying the first expression by the reciprocal of the second expression. This process is crucial in simplifying complex rational expressions and solving equations.
The Quotient of Rational Expressions
To find the quotient of two rational expressions, we follow a simple step-by-step process:
- Flip the second rational expression: We take the reciprocal of the second rational expression, which means we flip the numerator and the denominator.
- Multiply the first rational expression by the flipped second rational expression: We multiply the numerators together and the denominators together.
- Simplify the resulting expression: We simplify the resulting expression by canceling out any common factors in the numerator and the denominator.
Applying the Quotient Formula to the Given Rational Expressions
Let's apply the quotient formula to the given rational expressions:
We start by flipping the second rational expression:
Next, we multiply the first rational expression by the flipped second rational expression:
