Expert Answer

Step 1

We’ll answer the first question i.e. Q.9. Please submit a new question for the remaining.

Step 2

a.

Given fraction is:

The denominator is in factored form.

So the fraction is written using variables as:

Multiplying by (x-4)(x+2) on both sides:

Grouping x terms and constant terms:

Two polynomials are equal when the respective coefficients are equal. So, equating the coefficients:

Solving the system of equations for A and B:

Hence the partial decomposition of the fraction is given by:

Step 3

b.

Given fraction is:

The denominator is in factored form.

So the fraction is written using variables as:

Multiplying by x(x-3)2 on both sides:

This can be solved by plugging different values for x.

Plugging x=0,

 

Plugging ...
