Please give step by step solution please​

Answer 1

Answer:

a^2/(x-a)+b^2/(x-b)+c^2/(x-c)+a+b+c/a/(x-a)+b/(x-b)+c/(x-c)

=a{a/(x-a)+1}+b{b/(x-b )+1}+c{c/(x-c)+1}/a/(x-a)+b/(x-b)+c/(x-c)

=ax/(x-a)+bx/(x-b)+cx/(x-c)/a/(x-a )+b/(x-b )+c/(x-c)

=x{a/(x-a)+b/(x-b)+c/(x-c)}/a/(x-a)+b/(x-b)+c/(x-c)

=x
