Question

square the difenrence between 3m and 2n.

Answer 1

Answer:

Step-by-step explanation:

(2m+3n)square -(3m +2n)square

= [( 2m)square + (3n)square+2(2m) (3n)] - [(3m)square +(2n)square + 2(3m) (2n)]

= [ (4m square +9n square + 12 mn) - (9m square + 4n square + 12mn)]

= ( 4m square + 9n square + 12 mn - 9m square - 4n square -12 mn)

= ( -5m square +5n square + 0)

= [ -5(m square - n square)]

= [ -5(m+n) (m-n) ]
