Homework Help: Inverse Fourier, can't factor denominator, can't use partial frac.

  1. Mar 20, 2012 #1
    1. The problem statement, all variables and given/known data

    Inverse fourier of:
    [ jω+2 ] / [ (jω)2 +5jω+9 ] where j = sqrt(-1)

    I tried using partial fractions but the denominator can't be factored...I tried completing the square on the denominator but I get a sum of squares.

    What can I try? Im sure I don't have to use the formal definition using the integral, there has to be a way of manipulating it to be able to use the table.

    thank you!

    Why would you say the denominator can't be factored? It is just a quadratic in ω, so certainly has two roots.

    Alright, I will try to see if it leads me somewhere, do you think I'll be able to solve it this way? it seems like it will get messy
