Question

Find the remainder when x²+3x²+3x+1 is
divided by x+1
​

Answer 1

Step-by-step explanation:

$\huge\underline\mathcal\red{Answer}$

x+1=0

x=-1

put the value of X in equation

(-1)²+3(-1)²+3(-1)+1

1+3-3+1

4-3+1=1+1=2

2 is the answer of this question

Answer 2

Apply remainder theorem

=>x + 1 =0

=> x = - 1

Replace x by – 1 we get

=>x3+3x2 + 3x + 1

=>(-1)3 + 3(-1)2 + 3(-1) + 1

=> -1 + 3 - 3 + 1

=> 0

Remainder is 0
