SOLVING RATIONAL EQUATIONS Lesson 48

2
What are rational equations?

What do you do…

4
What do you do… Once youve cross multiplied, distribute any terms an solve for the missing variable. Ex: 2(x) = 3(x + 2) 2x = 3x + 6 -3x -x = 6 x = -6

5
What else could you do? If you need to add or subtract rational expressions to solve the equation, FIND A COMMON DENOMINATOR FOR ALL THE FRACTIONS. Once all the fractions have a common denominator, you can REMOVE THE DENOMINATORS AND MAKE AN EQUATION WITH JUST THE NUMERATORS.

What else could you do?

7
What else could you do? Ex: 1(x + 1) + 3x = 2(x + 1) x + 1 + 3x = 2x + 2 4x + 1 = 2x + 2 2x + 1 = 2 2x = 1 x = ½
