Try another version of this question Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Use partial fractions to find the power series of the function:
`(9x^2+61)/((x^2+9)(x^2+4))`
`sum_(n=0)^(oo)`
Be sure your variables match those in the question `(4/3^(2n+2) + 5/2^(2n+2))(-1)^n x^(2n)`
