Solving rational equations

• Extraneous solution: a possible solution that results from the process of solving, it will solve it but not satisfy the original equation
• When solving rational equations:

  • Eliminate the denominator
  • Be cautious of extraneous solutions that may arise during the process of solving
• Example of solving a rational equation:

  x + 2 / x + 2 = 3

  • Multiply all terms by the denominator (x + 2)
  • Simplify the equation to find the solution
