Here is the question:
I have posted a link there to this thread so the OP can view my work.PARTIAL FRACTIONS: How to solve this?
Let f(x) =
(x^2 + 7x − 6)/((x − 1)(x − 2)(x + 1))
(i) Express f(x) in partial fractions.
(ii) Show that, when x is sufficiently small for x4 and higher powers to be neglected,
f(x) = −3 + 2x − (3/2)x^2 + (11/4)x^3.
Please work it out step by step so I can figure out how to work out similar questions on my own.
