  1. Solving Trignometric Equations6.2 JMerrill, 2009

  2. Solving an algebraic equation

  3. Solving a Trigonometric Equation Using Algebra

  4. Solve Hint: Make the words match Quadratic: Set = 0 Combine like terms Factor—(same as 2x2-x-1)

  5. Solve Round to nearest hundredth Where did these 2 answers come from??? 

  6. Solve

  7. What You CANNOT Do • You cannot divide both sides by a common factor, if the factor cancels out. You will lose a root…

  8. Example Common factor—lost a root No common factor = OK

  9. You Do • Solve Check by graphing!
