# Multiply: (2x - 2y - 3), (x + y + 5)

**Solution:**

Given, __multiply__ (2x - 2y - 3), (x + y + 5)

⇒ (2x - 2y - 3) × (x + y + 5)

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

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

= 2x² - 2y² + 7x -13y - 15

**✦ Try This: **Multiply: (3a + 2b +5), (5a - 3b - 7)

Given, Multiply: (3a + 2b +5), (5a - 3b - 7)

⇒ (3a + 2b +5) × (5a - 3b - 7)

= 15a² - 9ab - 21a + 10ab - 6b² - 14b + 25a - 15b - 35

= 15a² + ab + 4a -29b- 6b² - 35
