Dear student
 
Pleas ask question properly as it is not clear where bracket is used and which term is in numerator and denominator. Please attach an image if possible.
 
I will be happy to help you

hello mrinal, the ques can simply be solved as follows:
1/(x^2-25) = 1/k[1/(x-5) – 1/(x+5)] 
or 1/(x^2-25) = 1/k[{(x+5) – (x – 5)}/(x-5)(x+5)]
or 1/(x^2-25) = 1/k[10/(x^2-25)]
or k = 10
kindly approve :))
