Multiply:(2x – 2y - 3), (x + y + 5)

1.	Multiply:(2x – 2y - 3), (x + y + 5)
Answer» The multiplication is as follows: (2x-2y-3)×(x + y + 5) = 2x.x + 2x.y + 2x.5-2y.x-2y.y-2y.5-3.x-3.y-3.5 = 2x² + 2xy + 10x-2xy-2y²-10y-3x-3y-15 = 2x²-2y² + 7x-7y-15 The product is = 2x²-2y² + 7x-7y-15

Answer»

The multiplication is as follows:

(2x-2y-3)×(x + y + 5)

= 2x.x + 2x.y + 2x.5-2y.x-2y.y-2y.5-3.x-3.y-3.5

= 2x² + 2xy + 10x-2xy-2y²-10y-3x-3y-15

= 2x²-2y² + 7x-7y-15

The product is = 2x²-2y² + 7x-7y-15
