Question

simply please help me anyone

Answer 1

Answer :

$\frac{m {}^{2} }{m - n} + \frac{n {}^{2} }{n - m }$

$\frac{m {}^{2} (n - m) + (m - n)n {}^{2} }{(m - n)(n - m)}$

$\frac{mn {}^{2} - m {}^{3} +mn {}^{2} - n {}^{3} }{m(n - m) - n(n - m)}$

$\frac{mn {}^{2} - m {}^{3} + mn {}^{2} - n {}^{3} }{mn - m {}^{2} - n {}^{2} + mn}$

By dividing

$mn + m + mn + n$

$2mn + m + n$

Answer is 2mn + m + n
