Answer:

3/(x +1) -4/(x +1)^2

Step-by-step explanation:

The partial fraction expansion will be of the form ...

A/(x+1)^2 +B/(x+1)

We can find the values of A and B by writing the sum of these terms:

= (A +B(x +1))/(x +1)^2

Then we require ...

B = 3

A +B = -1 ⇒ A = -4

So, the desired expansion is ...

3/(x +1) -4/(x +1)^2

nadya68 [22]

Answer:

38%

Step-by-step explanation:

Original price = $ 80

Price after reduction = $ 49.60

Reduction = 80 - 49.60 = $30.40

Percentage of decrease = $\frac{reduction price}{original price}*100$

$= \frac{30.40}{80}*100\\\\=\frac{3040}{80}$

= 38%
