Question

Answer the above question

Answer 1

$\frac{l}{m} + \frac{2}{m-1} + \frac{3}{m-2}$

lcm = $m^{3} - 3m^{2} + 2m$

⇒ $\frac{l ( m^{2} -3m +2)}{m(m^{2} - 3m + 2) } + \frac{2(m^{2} - 2m)}{m-1(m^{2}-2m) } + \frac{3(m^{2} - m)}{m-2(m^{2} - m)}$

⇒$\frac{ lm^{2} - 3lm + 2l +2m^{2}  - 4m +3m^{2} - 3m}{m^{3}-3m^{2} + 2m }$

⇒$\frac{lm^{2} - 3lm + 2l +5m^{2} -7m^{2}} {m^{3} - 3m^{2} + 2m }$

hope this helps you
