Reduce the expression by cancelling the common factors.

Cancel the common factor.

Rewrite the expression.

Rewrite as .

Since both terms are perfect squares, factor using the difference of squares formula, where and .

Since the variable is in the denominator on the left side of the equation, this can be solved as a ratio. For example, is equivalent to .

Find the LCD of the terms in the equation.

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

Since contain both numbers and variables, there are two steps to find the LCM. Find LCM for the numeric part then find LCM for the variable part .

The LCM is the smallest positive number that all of the numbers divide into evenly.

1. List the prime factors of each number.

2. Multiply each factor the greatest number of times it occurs in either number.

The number is not a prime number because it only has one positive factor, which is itself.

Not prime

The LCM of is the result of multiplying all prime factors the greatest number of times they occur in either number.

The factors for are , which is multiplied by each other times.
