Partial fraction of this expression?

  1. Jan 16, 2005 #1
    hi everyone

    i have a proplem with this excercise:
    f(t)= (t+1)/(t^2 + 8t + 16)
    Here what i started:

    (t+1)/(t^2 + 8t + 16) = (t+1)/(t+4)^2

    (t+1)/(t+4)^2 = K1/(t+4) + K2/(t+4)^2

    i am stuck from here, anyone please help me, thanks first

    What are you trying to do??
    Put this
    [tex] \frac{t+1}{(t+4)^{2}} [/tex]

    under this form:
    [tex] \frac{A}{t+4}+\frac{B}{(t+4)^{2}} [/tex]

    ??

    How about writing
    [tex] t+1=t+4-3 [/tex]

    ??

    Daniel.
