Question

find the factors of( X - 1) (X + 1) (x - 3)( X + 3) + 4 x^2​

Answer 1

Answer:

The zero of x+1 is −1

Let p(x)=x

4

+x

3

+x

2

+x+1

Then, p(−1)=(−1)

4

+(−1)

3

+(−1)

2

+(−1)+1

=1−1+1−1+1=1

Since, p(−1)



=0

Therefore, by Factor theorem, x+1 is not a factor of x

4

+x

3

+x

2

+x+1
