Answer:

-3mn²+ 4m²n²

Step-by-step explanation:

=3mn²+ 4m²n² +(-5mn²) + (-mn²)

= 3mn²+4m²n² -5mn² -mn²

= 3mn² -5mn² -mn² + 4m²n²

= 3mn²-6mn² + 4m²n²

= -3mn² +4m²n²

HOPE THIS HELPS YOU.

Answer: mn^{2} (4m-3)

Step-by-step explanation:

3mn^{2} + 4m^{2}n^{2} + (-5mn^{2}) + (-mn^{2})

= 3mn^{2} + 4m^{2} n^{2} - 6mn^{2}

= 4m^{2} n^{2} - 3mn^{2} (adding and subtracting the like terms)

Now, mn^{2} can be taken common from each term of the above expression. This gives:

mn^{2} (4m-3)

which is the required answer.
