  1. Factoring Polynomials Ch. 6 Quiz Next

  2. Directions This is a short five question multiple choice quiz. Questions will cover the types of factoring that we have studied earlier this week. Try not to use your calculator, although you may use scratch paper to work out problems and then click on the Letter of your choice to see if you were correct. Next

  3. 1. Factor Completely x²-13x-14 A. (x+14)(x-1) B. (x-7)(x-2) C. (x-14)(x+1) D. (x+7)(x-2)

  4. Correct You chose the right answer! Good job! Quit Quiz Next

  5. Incorrect You chose the wrong answer. Here is a sample solution to a similar problem. X²-7x-8 -8·1=-8, when -8 and 1 are added together you get -7. So therefore the answer is (x-8)(x+1). Quit Quiz Back

  6. 2. Factorm²+m-90 A. (m-9)(m+10) B. (m+9)(m+10) C. (m+9)(m-10) D. (m-9)(m-10)

  7. Correct You chose the right answer! Good job! Quit Quiz Next

  8. Incorrect You chose the wrong answer. Here is a sample solution to a similar problem. m²+m-30 Find a product that has a sum of 1. Positive 6 times negative 5 equals -30, when 6 and -5 are added together you get 1. (m+6)(m-5) Quit Quiz Back

  9. 3.Factorz²-49 A. (z-6)(z+7) B. (z-7)(z+7) C. (z+9)(z-5) D. (z-9)(z+6)

  10. Correct You chose the right answer! Good job! Quit Quiz Next

  11. Incorrect You chose the wrong answer. Here is a sample solution to a similar problem. Z²-36 This equation is of a perfect square, so therefore take the square root of 36. This is the final answer. (z-6)(z+6) Quit Quiz Back

  12. 4.Factor by Grouping8r³-64r²+r-8 A. (8r²-1)(r+8) B. 8(r²+1)(r-8) C. (8r²+1)(r-8) D.(8r²-64)(r+8)

  13. Correct You chose the right answer! Good job! Quit Quiz Next

  14. Incorrect You chose the wrong answer. Here is a sample solution to a similar problem. 6r³-36r²+r-6 6r²(r-6)+1(r-6) (6r²+1)(r-6) Quit Quiz Back

  15. 5.Factor by Grouping21k³-84k²+15k-60 A. (21k²-15)(60k+84) B. (21k²+15)(60k-84) C. 3(7k²-5)(k+4) D. 3(7k²+5)(k-4)

  16. Correct You chose the right answer! Good job! Quit Quiz Next

  17. Incorrect You chose the wrong answer. Here is a sample solution to a similar problem. 63k³-54k²+105k-90 3(21k³-18k²+35k-30) 3[3k²(7k-6)+5(7k-6)] 3(3k²+5)(7k-6) Quit Quiz Back
