  1. Equations Objectives for today’s lesson : • Solving Equations using Trial & Improvement

  2. Objective: Trial & Improvement Example Solve x2 + x = 420

  3. Trial & Improvement Example Solve x2 + x = 420

  4. Trial & Improvement Example Solve x2 + x = 420

  5. Trial & Improvement Example Solve x2 + x = 420

  6. Trial & Improvement Example Solve x2 + x = 420

  7. Trial & Improvement Example Solve x2 + x = 420

  8. Now Solve x2 + x = 30 Example Solve x2 + x = 420 x=20

  9. Trial & Improvement Try Solve x2 + x = 30

  10. Trial & Improvement Questions to try 1. x2 + x = 240 2. x2 – x = 702 3. x2 + 2x = 143 4. x3 – 1 = 10 (this does not have an exact answer)

  11. Trial & Improvement Questions to try x2 – x = 702 x = 27 x3 + 2x = 135 x = 5 x3 + 2x = 1752 x = 12 x3 – 1 = 10 x = 2.2
