TO FACTORISE : - m ( m - 3 ) - n ( n - 1 ) 

SOLUTION -

⇒m ( m - 3 ) - n ( n - 1 ) 
⇒ ( m - 3 ) ( n - 1 ) ( m - n )                                  ( By  Multiplying the terms )
⇒ ( mm - m - 3n + 3 ) ( m - n )
⇒ m²n - m² - 3mn + 3m - mn² + mn + 3n² - 3n 
⇒ m²n - m² - 2mn + 3m - mn² + 3n² - 3n
1 5 1
yes
it is wrong, there should be no plus or minus signs in the answer
u mean i have to find ans of m and n
