Answer:
700
Step-by-step explanation:
guess be like
Always use PEMDAS as order of operations:
parentheses before exponents before multiplication before division before addition before subtraction = P.E.M.D.A.S.
Since we have only addition, subtraction, multiplication, and division, we need to do:
M>D>A>S
5 + 5 - 2 * 7 / 8 + 98 - 64
5 + 5 + [-2 * 7] / 8 + 98 - 64. first
5 + 5 + [-14 / 8] + 98 - 64. second
(10) + [-1.75 + 98] - 64. third
[10 + 96.25] - 64. fourth
106.25 - 64. last
42.25
????
we are given
![\int \:\frac{4}{\left(x+1\right)\left(x-1\right)^2}dx](https://tex.z-dn.net/?f=%20%20%5Cint%20%5C%3A%5Cfrac%7B4%7D%7B%5Cleft%28x%2B1%5Cright%29%5Cleft%28x-1%5Cright%29%5E2%7Ddx%20%20%20)
we can use partial fraction method
firstly , we will find partial fraction
![\frac{1}{\left(x+1\right)\left(x-1\right)^2}:\quad \frac{1}{4\left(x+1\right)}-\frac{1}{4\left(x-1\right)}+\frac{1}{2\left(x-1\right)^2}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B1%7D%7B%5Cleft%28x%2B1%5Cright%29%5Cleft%28x-1%5Cright%29%5E2%7D%3A%5Cquad%20%5Cfrac%7B1%7D%7B4%5Cleft%28x%2B1%5Cright%29%7D-%5Cfrac%7B1%7D%7B4%5Cleft%28x-1%5Cright%29%7D%2B%5Cfrac%7B1%7D%7B2%5Cleft%28x-1%5Cright%29%5E2%7D%20%20)
![=4\cdot \int \:\frac{1}{4\left(x+1\right)}-\frac{1}{4\left(x-1\right)}+\frac{1}{2\left(x-1\right)^2}dx](https://tex.z-dn.net/?f=%20%3D4%5Ccdot%20%5Cint%20%5C%3A%5Cfrac%7B1%7D%7B4%5Cleft%28x%2B1%5Cright%29%7D-%5Cfrac%7B1%7D%7B4%5Cleft%28x-1%5Cright%29%7D%2B%5Cfrac%7B1%7D%7B2%5Cleft%28x-1%5Cright%29%5E2%7Ddx%20%20%20)
now, we can distribute integral
![=4\left(\int \frac{1}{4\left(x+1\right)}dx-\int \frac{1}{4\left(x-1\right)}dx+\int \frac{1}{2\left(x-1\right)^2}dx\right)](https://tex.z-dn.net/?f=%20%20%3D4%5Cleft%28%5Cint%20%5Cfrac%7B1%7D%7B4%5Cleft%28x%2B1%5Cright%29%7Ddx-%5Cint%20%5Cfrac%7B1%7D%7B4%5Cleft%28x-1%5Cright%29%7Ddx%2B%5Cint%20%5Cfrac%7B1%7D%7B2%5Cleft%28x-1%5Cright%29%5E2%7Ddx%5Cright%29%20)
now, we can solve each
![=4\left(\frac{1}{4}\ln \left|x+1\right|-\frac{1}{4}\ln \left|x-1\right|-\frac{1}{2\left(x-1\right)}\right)](https://tex.z-dn.net/?f=%20%3D4%5Cleft%28%5Cfrac%7B1%7D%7B4%7D%5Cln%20%5Cleft%7Cx%2B1%5Cright%7C-%5Cfrac%7B1%7D%7B4%7D%5Cln%20%5Cleft%7Cx-1%5Cright%7C-%5Cfrac%7B1%7D%7B2%5Cleft%28x-1%5Cright%29%7D%5Cright%29%20%20)
