The partial fraction decomposition of 9 x 11 6 x 2 23 x 21 can be written in the form of f ( x ) 2 x 3 g ( x ) 3 x 7 , where

Step-by-step explanation:

The question is unreadable, however the real polynomial is:

The polynomial fraction is:

And the decomposition is:

The solution is as follows:

Substitute the expression for P

Expand the numerator of the polynomial

Take LCM

Cancel out both denominators

Represent f(x) as A and g(x) as B

Open bracket

By comparison:

---- (1)

---- (2)

Make B the subject in (1)

Substitute in (2)

Multiply through by 2

Collect Like Terms

Recall that:

A = -1 and B = 6

---- (1)

---- (2)

So:

And the decomposition is:
