  1. Math IV – Unit ThreeRational Functions Solving Rational Equations by Cross Multiplication

  2. Checking for extraneous solutions Check to see if solution produces a zero in the denominators

  3. Rational Equations by cross multiplication (Only where in this form) a b = c d

  4. Solving Rational EquationsCross-Multiplication 3(x + 4) = 5(x + 3) 3x + 12 = 5x + 15 3x – 5x = -12 + 15 -2x = 3 x = -3/2
