Multiply: (x² - 5x + 6), (2x + 7)

Solution:

Given, multiply (x² - 5x + 6), (2x + 7)

⇒ (x² - 5x + 6) × (2x + 7)

= 2x³ + 7x² - 10x² - 35x + 12x + 42

= 2x³ - 3x² - 23x + 42

✦ Try This: Multiply: (2a² +3a -5 ), (5a - 4)

Given, Multiply: (2a² +3a -5 ), (5a - 4)

= (2a² +3a -5 )×(5a - 4)

= 10a³ - 8a² + 15a² - 12a - 25a +20

= 10a³ + 7a² - 37a + 20
