## How do you solve rational equations?

- 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.

## How do you solve rational equations with different denominators?

One way of solving rational equations with unlike denominators is to multiply both sides of the equation by the least common multiple of the denominators of all the fractions contained in the equation. This eliminates the denominators and turns the rational equation into a polynomial equation.

## What are the rules or steps to follow in solving rational expressions?

Step 1: Factor both the numerator and denominator of the fraction. Step 2: Reduce the fraction. Step 3: Rewrite any remaining expressions in the numerator and denominator. Step 1: Factor both the numerator and denominator of the fraction.
