Question

find the remainder when x4+x3-2x2-x-1 is divided by x-1​

Answer 1

Answer:

x=1,

(1)^4+1^3-2×2-1-1

1+1-4-1-1

-4 answer

Answer 2

Step-by-step explanation:

f(x) is divided by x-a the remainder is f(a).This is the remainder theorm

f(x)=x⁴+x³-2x²-x-1

x-a=x-1

a=1

Remainder is f(a)

f(x)=x⁴+x³-2x²-x-1

f(a)=f(1)=(1)⁴+(1)³-2(1)²-(1)-(1)

f(1)=1+1-2-1-1

f(1)= -2

-2 is the remainder
