Homework Help: Again, Infinite Limit

  1. May 18, 2010 #1
    1. The problem statement, all variables and given/known data

    [tex] \lim_{t \to 3^{+}} \frac {y+1}{(y-2)(y-3)} [/tex]

    2. Relevant equations



    3. The attempt at a solution

    I thought that this problem looked pretty straight forward but i am obviously doing something wrong. What I did was:

    multiply the binomials:

    [tex] \lim_{t \to 3^{+}} \frac {y+1}{y^{2}-5y+5} [/tex]

    and then apply the limit:

    [tex] \frac {3+1}{3^{2}-15+5} = \frac {4}{-1} = -4 [/tex]

    but this is WAY off because the answer is suppose to be infinity, so what did I forgot from the lesson?....

    Check your multiplication again.
