By using formula --
a^2 - b^2 = ( a +b )(a -b )
we get --
( 3x +2y + 5x - 3y ) ( 3x + 2y -5x + 3 y )
= ( 8x - y ) ( -2x +5y ) Ans.
a^2 - b^2 = ( a +b )(a -b )
we get --
( 3x +2y + 5x - 3y ) ( 3x + 2y -5x + 3 y )
= ( 8x - y ) ( -2x +5y ) Ans.

9x²+4y²+12xy-(25x²+9y²-30xy)
9x²+4y²+12xy-25x²-9y²+30xy
-16x²-5y²+42xy
-[16x²-42xy+5y²]
-[16x²-40xy-2xy+5y²)
-[8x(2x-5y)-y(2x-5y)]
-1(8x-y)(2x-5y)
9x²+4y²+12xy-25x²-9y²+30xy
-16x²-5y²+42xy
