\boxed{\underline{\textsf{Solution :}}}

\textsf{Now,}\:\small{\frac{1}{(x-1)(x-2)}+\frac{1}{(x-2)(x-3)}+\frac{1}{(x-3)(x-4)}}

=\small{\frac{(x-1)-(x-2)}{(x-1)(x-2)}+\frac{(x-2)-(x-3)}{(x-2)(x-3)}+\frac{(x-3)-(x-4)}{(x-3)(x-4)}}

=\small{\frac{1}{x-2}-\frac{1}{x-1}+\frac{1}{x-3}-\frac{1}{x-2}+\frac{1}{x-4}-\frac{1}{x-3}}

=-\frac{1}{x-1}+\frac{1}{x-4}

=\frac{-(x-4)+(x-1)}{(x-1)(x-4)}

=\frac{-x+4+x-1}{(x-1)(x-4)}

=\frac{3}{(x-1)(x-4)}

\textsf{Given that,}\:\frac{3}{(x-1)(x-4)}=\frac{1}{6}

\to (x-1)(x-4)=3*6

\to x^{2}-5x+4=18

\to x^{2}-5x-14=0

\to x^{2}-7x+2x-14=0

\to x (x-7)+2 (x-7)=0

\to (x-7)(x+2)=0

\textsf{Either, x - 7 = 0 or, x + 2 = 0}

\textsf{i.e., x = 7 , x = - 2}

\textsf{which is the required solution.}

Swarup1998: :)
AMGTHEGREAT: I am not understanding the first step
Swarup1998: 1 = (x - 1) - (x - 2) = x - 1 - x + 2 = - 1 + 2 = 1
AMGTHEGREAT: ok
AMGTHEGREAT: just a min I am checking it
Swarup1998: sure do :)
AMGTHEGREAT: plz Follow me
Swarup1998: Thanks for the Brainliest :)
AMGTHEGREAT: it's OK
