  3. Jeopardy Board Final Jeopardy

  4. Add and Subtract Polynomials - 100 (2x2 + 5x) + (7x2 + 3x + 11) Board Answer

  5. Add and Subtract Polynomials - 100 (2x2 + 5x) + (7x2 + 3x + 11) Since you are adding the two polynomials the parentheses mean nothing 2x2 + 5x + 7x2 + 3x + 11 Combine like terms 9x2 + 8x + 11 Board

  6. Add and Subtract Polynomials - 200 (x2 + 8x – 11) + (x3 + 3x2 + 11) Board Answer

  7. Add and Subtract Polynomials - 200 (x2 + 8x – 11) + (x3 + 3x2 + 11) Since you are adding the two polynomials the parentheses mean nothing x2 + 8x – 11 + x3 + 3x2 + 11 Combine like terms x3 + 4x2 + 8x + 0 x3 + 4x2 + 8x Board

  8. Add and Subtract Polynomials - 300 (2x2 – 5x3) – (7x3 – 2x2 + 11) Board Answer

  9. Add and Subtract Polynomials - 300 These signs must change (2x2 – 5x3) – (7x3 – 2x2 + 11) Since you are subtracting the two polynomials the parentheses are very important 2x2 – 5x3 – 7x3 + 2x2 – 11 Combine like terms -12x3 + 4x2 – 11 Board

  10. Add and Subtract Polynomials - 400 3(9x2 – 5x) – (x3 – 2x2 + x – 4) Board Answer

  11. Add and Subtract Polynomials - 400 Distribute the 3 These signs must change 3(9x2 – 5x) – (x3 – 2x2 + x – 4) Since you are subtracting the two polynomials and multiplying the first by 3, the parentheses are very important 27x2 – 15x – x3 + 2x2 – x + 4 Combine like terms -x3 + 29x2 – 16x + 4 Board

  12. Add and Subtract Polynomials - 500 (x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6) Board Answer

  13. Add and Subtract Polynomials - 500 These signs must change (x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6) x + 3 + 7x2 – 5x – 3x3 + x2 + 4x + 6 Since you are adding the first two polynomials the parentheses mean nothing. Combine like terms -3x3 + 8x2 + 0x + 9 -3x3 + 8x2 + 9 However, you are subtracting the third so the parentheses are very important Board

  14. Exponent Rules - 100 (x3)(x2) Board Answer

  15. Exponent Rules - 100 (x3)(x2) x3 = x  x  x x2 = x  x (x3)(x2) = x  x  x x  x = x5 Board

  16. Exponent Rules - 200 (5x5)(7x7) Board Answer

  17. Exponent Rules - 200 (5x5)(7x7) 5x5 = 5  x x  x  x x 7x7 = 7  x x  x  x  x  x x (5x5)(7x7) = 5  x x  x  x x 7  x x  x  x  x  x x= 35x12 Board

  18. Exponent Rules - 300 Board Answer

  24. Scientific Notation - 100 Rewrite in scientific notation 23,000,000 Board Answer

  25. Scientific Notation - 100 Rewrite in scientific notation 23,000,000 The decimal is at the end of a whole number 23 000 000 = 2.3 x 107   In scientific notation the decimal goes after the first digit. You need to know how many place values you have to move the decimal Board

  26. Scientific Notation - 200 Rewrite in scientific notation 0.000345 Board Answer

  27. Scientific Notation - 200 Rewrite in scientific notation 0.000345 You can see where the decimal is 0.000345 = 3.45 x 10-4  In scientific notation the decimal goes after the first digit. You need to know how many place values you have to move the decimal Board

  28. Scientific Notation - 300 Rewrite in standard form 8.76 x 104 Board Answer

  29. Scientific Notation - 300 Rewrite in standard form 8.76 x 104 8.76 00 = 87,600  Move the decimal 4 places Add two zeros Board

  30. Scientific Notation - 400 Rewrite in standard form 2.0406 x 10-5 Board Answer

  31. Scientific Notation - 400 Rewrite in standard form 2.0406 x 10-5 0000 2.0406 = 0.000020406  Move the decimal 5 places Add four zeros Board
