# Thread: sum of power series problem

1. ## sum of power series problem

Express the function as the sum of a power series by first using partial fractions, find the interval of convergence.

f(x) = 3/(x^2 +x - 2)

thanks for any help with this one.

..partial fraction would be: 3/(x-1) + 3/(x+2)
i think.
