Subtract the product of 2x(5x – y) from product of 3x(x+2y)

1.	Subtract the product of 2x(5x – y) from product of 3x(x+2y)
Answer» 3x(x + 2y) – 2x(5x – y) = (3x × x + 3x × 2y) - (2x × 5x – 2x × y) = 3x² + 6xy – (10x² – 2xy) = 3x² + 6xy- 10x² + 2xy = 8xy – 7x²

Answer»

3x(x + 2y) – 2x(5x – y)

= (3x × x + 3x × 2y) - (2x × 5x – 2x × y)

= 3x² + 6xy – (10x² – 2xy)

= 3x² + 6xy- 10x² + 2xy

= 8xy – 7x²
