Remember finding the Least Common Denominator (LCD) to add/subtract fractions?
To find the LCD, you must factor each number/polynomial and find the Least Common Multiple (LCM) of the denominators. The LCM contains each factor the greatest # of times it appears as a factor.
Well, you must do this same process to add/ subtract polynomials! 1)

Look carefully at each problem to see if it is addition, subtraction, multiplication or division. For addition and subtraction you need a ___________________ _____________________. For multiplication, _____________________ first, then _____________________. For division, multiply by the _______________________ of the second fraction.
