Rational expressions are fractions containing polynomials. They can be simplified much like numeric fractions. To simplify a rational expression, first determine common factors of the numerator and denominator, and then remove them by rewriting them as expressions equal to 1.
How do you solve rational algebraic expressions?
- Solution:
- Step 1: Factor all denominators and determine the LCD.
- Step 2: Identify the restrictions. In this case, they are x≠−2 x ≠ − 2 and x≠−3 x ≠ − 3 .
- Step 3: Multiply both sides of the equation by the LCD.
- Step 4: Solve the resulting equation.
- Step 5: Check for extraneous solutions.
What is the example of rational equation?
Equations that contain rational expressions are called rational equations. For example, 2x+14=7x 2 x + 1 4 = 7 x is a rational equation. Rational equations can be useful for representing real-life situations and for finding answers to real problems.
What is example of rational algebraic expression?
Or in other words, it is a fraction whose numerator and denominator are polynomials. These are examples of rational expressions: x1. x + 5 x 2 − 4 x + 4 \dfrac{x+5}{x^2-4x+4} x2−4x+4x+5.
How do you solve rational expressions step by step?
The steps to solve a rational equation are:
- Find the common denominator.
- Multiply everything by the common denominator.
- Simplify.
- Check the answer(s) to make sure there isn’t an extraneous solution.
