What is the product of a+3 and −2a2+15a+6b2? −2a3+9a2+45a+24b2
−2a3+21a2+45a+24b2
−2a3+9a2+45a+6ab2+18b2
−2a3+21a2+45a+6ab2+18b2

Step-by-step explanation:

(a + 3)×(−2a² + 15a + 6b²) =

= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =

= -2a³ + 15a² + 6ab² - 6a² + 45a + 18b² =

= -2a³ + 9a² + 6ab² + 45a + 18b²
