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
4 - 8x = -1 + 1 - 9x + 8
Combine like terms.
4 - 8x = -9x + 8
Add 9x to both sides.
4 + x = 8
Subtract 4 from both sides.
x = 4
The x-intercept is equal to 4.
