# How do you add rational expressions step by step?

## How do you add rational expressions step by step?

Adding or subtracting rational expressions is a four-step process:

- Write all fractions as equivalent fractions with a common denominator.
- Combine the fractions as a single fraction that has the common denominator.
- Simplify the expression in the top of the fraction.
- Reduce the fraction to lowest terms.

## How do you subtract rational expressions step by step?

**How do you sum a rational algebraic expression?**

To add rational expressions, they must have a common denominator. When the denominators are the same, you add the numerators and place the sum over the common denominator. To add rational expressions with a common denominator, add the numerators and place the sum over the common denominator.

**When adding and subtracting rational expressions my first step should be to?**

Adding or subtracting rational expressions is a four-step process:

- Write all fractions as equivalent fractions with a common denominator.
- Combine the fractions as a single fraction that has the common denominator.
- Simplify the expression in the top of the fraction.
- Reduce the fraction to lowest terms.

### How do you simplify rational expressions in algebra 2?

- Step 1: Factor the numerator and the denominator.
- Step 2: List restricted values.
- Step 3: Cancel common factors.
- Step 4: Reduce to lowest terms and note any restricted values not implied by the expression.

### What are the steps in solving addition and subtraction of rational expressions?

**How do you subtract fractions in algebra 2?**

To subtract fractions:

- Step 1 Find the least common denominator of the two fractions.
- Step 2 Change each fraction to an equivalent fraction having the least common denominator.
- Step 3 Find the difference of the numerators and place this result over the least common denominator.

**How can you get the difference of the two rational numbers with like denominators?**

To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator.

## Why is it important to learn the concept of adding rational expressions?

Rational equations can be used to solve a variety of problems that involve rates, times and work. Using rational expressions and equations can help us answer questions about how to combine workers or machines to complete a job on schedule.
