express the function as the sum of a power series by first using partial fractions. f(x) = (x + 7) /(2x^2 − 11x − 6 )
f(x) = ∞ n = 0 find the interval of convergence. (enter your answer using interval notation.)

Factorize the denominator:

Then we look for coefficients such that

So we have

Recall that for , we have

Now,

for , or , and

for , or .

The interval of convergence for is the intersection of these two intervals,
