​

Answer 1

Answer:

hope it will help you:-)

Answer 2

Answer:

3x² + 4x + 5

Step-by-step explanation:

⇒ (3x³ + 16x² + 21x + 20) ÷ (x+4)

Factorization, and finding the common factor (x+4):

⇒ (3x³ + 12x² + 4x²  + 16x + 5x + 20) ÷ (x+4)

⇒ {3x²(x + 4) + 4x(x + 4) + 5(x + 4)} ÷ (x+4)

⇒ {(3x² + 4x + 5)(x + 4)} ÷ (x+4)

⇒ (3x² + 4x + 5)
