Question

Find the remainder when X cube+3xsquare+3x+1 is divided by (X+1)

Answer 1

Answer:

x+1 = 0

= x = -1

Substituting the value of x in the given equation.

$= { - 1}^{3} + {3 (- 1)}^{2} + 3 (- 1) + 1$

= -1+3-3+1 = 0

Hence, the remainder is 0 as (x+1) is a factor of the given polynomial.
