M 1010 §6.6 (Math 1010) 1/1 §6.6 Solving Rational Equations Notes To determine if a real value is a solution to a rational equation, substitute that value for the unknown at each step. Example: Are x = 1 or x = 10 solutions to 5 − 1 = 2? x −3 To solve a rational equation, multiply each side by the least common demoninator. Domain restrictions may not allow some solutions you find, so it is vital to check your work! M 1010 §6.6 (Math 1010) 2/1 §6.6 Solving Rational Equations # 1 Exercise # 23.
