Hi there, I know that when I am to guess a solution to to a polynomial for g(t) that I guess Ax^n + Bx^n-1... when the highest power of the polynomial is n but what is my guess supposed to be if the power of n is negative?(adsbygoogle = window.adsbygoogle || []).push({});

ex.

y'' + 4y' + 4y =t^-2*e^(-2t)

so far my guess is,

A*e^(-2t)(B*?...)
