asked by trent
  1. Ok, trent, so if solving for m use this formula: (Google quadratic formula to see formula) so, -b should be 24, b^2 should be -24^2, a should be 4 and c should be 36. The answer should be m=3. -------But if you are to foil this, then 4m^2-24m+36 will be (4m-12)(m-3).

  2. I would divide by 4 to get
    m^2 - 6m + 9 = 0 , and now see it as a perfect square
    (m-3)^2 = 0
    m-3 = 0
    m = 3
