Answer 1

Answer:

-27/8

Step-by-step explanation:

Given :

f(x) = x³ + 3x² + 3x + 1

g(x) = 5 + 2x

Apply remainder theorem

=> 5 + 2x = 0

=> 2x = - 5

=> x = - 5/2

Replace x by -5/2 we get

=> x³ + 3x² + 3x + 1

=> (-5/2)³ + 3(-5/2)² + 3(-5/2) + 1

=> -125/8  + 75/4 - 15/2 + 1

=> -27/8

Remainder is -27/8

Hope it helps!
