the remainder of P(x) when divided by x + 2 is obtained by P(x= -2)
= (-2)⁻⁴ - 4 (-2)³ + 3 (-2) -1
= 41
we can do the division as :
quotient: x³ - 6 x² + 12 x - 21
x+2 ) x⁴ - 4 x³ + 3 x - 1 ( x³ - 6 x² + 12 x - 21
x⁴ + 2 x³
========
- 6 x³ + 3x
- 6 x³ - 12 x²
===========
3x + 12 x²
24 x + 12 x²
==============
-21 x -1
-21 x - 42
============
41
===============================
A simpler way of dividing the polynomial with x+2 is :
x + 2 ) 1 -4 0 3 -1
-2 12 -24 42
==============================
1 -6 12 -21 41
So quotient : x³ - 6x² + 12 x - 21 and remainder 41
= (-2)⁻⁴ - 4 (-2)³ + 3 (-2) -1
= 41
