The result obtained on subtracting the product of 2x and (x - 3y) from (5x + 3y) and (2y + 1) is ____.
16xy + 6y2 - 2x2 + 5x + 3
16xy + 6y2 - 2x2 + 5x - 3y
16xy + 6y2 - 2x2 + 5x + 3y
16xy + 6y2 - 2x2 + 5x
(5x + 3y)(2y + 1) - 2x(x -3y) =10xy + 5x +6y 2 +3y -2x2 + 6xy =16xy + 6y2 - 2x2 + 5x + 3y
On subtracting (x+2y) from (4x+5y), the result obtained is 3x+2y.
