Chapter 6 - Section 6.2 - Adding and Subtracting Rational Expressions - Exercise Set: 104

Answer

To subtract rational expressions with different denominators, change the terms first to similar rational expressions by using the $LCD.$ Once the denominators are the same, subtract the expressions by subtracting the numerators and then copying the common denominator. Note that if the numerator of the second term contains more than one term, subtracting by this numerator involves reversing the sign of the terms.
