Question

What will be the remainder of x³ + 3x² + 3x +1, when it is divided by (x+1)?​

Answer 1

Answer:

Quotient=x² + 2x + 1

Remainder = 0

Explanation:

x + 1 ) x³ + 3x² + 3x + 1( x² + 2x + 1

(-)x³ + x²

2x² + 3x

(-)2x² + 2x

x + 1

(-) x + 1

0

Answer 2

Answer:

-1

Step-by-step explanation:

x+1=0

then,x=-1

putting x=-1in the polynomial

we get,

${ - 1}^3 + 3( { - 1}^2)+ 3( - 1){?} + 1 = - 1 + 3 - 3 + 1 = 0$

there for ,

-1 is the remainder when the plolynomial divided by( x-1)
