Quiz 1.14
Question:

In the next three questions, you will be asked to factor polynomials. Express your answer as a product of polynomials with integer coefficients. For example, if you were asked to factor –9x2 + 21x – 12, you should enter either -3(3x-4)(x-1) or -3(x-1)(3x-4).

  • Do not include spaces in your answer
  • Any constant factors should appear first
  • The terms of each factor should be in order of decreasing degree. That is, (3x-4), not (4-3x).
  • If the polynomial is prime, then your answer should be "prime" (with or without quotes).
Factor 81x2 – 64. Do not include spaces in your answer. If the polynomial is prime, then enter "prime"
