Answer:

Step 1: Factor the denominator of each fraction to help find the LCD.

Step 2: Find the least common denominator (LCD). Click on the link if you need to review the STEPS for finding the LCD.

Step 3: Find the new numerator for each fraction. To find the new numerators for each fraction compare the denominator of each of the original fractions to the LCD and write down everything different about the LCD in the numerator of that fraction. You should also consider using the letters “LCD” in the denominators instead of the actual LCD because this will make it less tempting to reduce the fractions.

Step 4: Combine the fraction by adding or subtracting the numerators and keeping the LCD. When subtracting, notice that the subtraction sign is moved into the numerator so it can be distributed later if needed.

Step 5: Simplify the numerator by distributing and combining LIKE terms.

Step 6: Factor the numerator if you can and replace the letters “LCD” with the actual LCD.

Step 7: Simplify or reduce the rational expression if you can. Remember to reduce rational expressions the FACTORS must be exactly the same in both the numerator and denominator. Click on the link if you need to review the steps for SIMPLIFYING Rational Expressions.
