Question

x-1) x³+x²-x-1( =what give me fast answer​

Answer 1

Answer:

(x^2-1)(x+1)

Step-by-step explanation:

x³+x²-x-1

=x^2(x+1)-1(x+1)

=(x^2-1)(x+1)

Answer 2

Answer:

$(x+1)(x-1)(x+1)$

Step-by-step explanation:

first we can take value of x which is the factor of

i will take the value of x = 1 then, (x - 1)

divide (x - 1) with x³+x²-x-1 and take quatient and factorise

answer is $x^2 +2x+1$

factorise this polynomial

=> $x^2+x+x+1$

=> $x(x+1)+1(x+1)$

=> $(x+1)(x+1)$

then the factor of x³+x²-x-1 is $(x+1)(x-1)(x+1)$
