Question

(1+x)(1-x)(1+x²) solve it

Answer 1

Answer:

The answer will be (1 - $x^{4}$).

Step-by-step explanation:

We have given;

                       = (1+x)(1-x)(1+x²);

Now, multiply it;

                       = (1-x²)(1+x²);                (using (x+y)(x-y) identity)

Now, multiply the remaining terms;

                       = 1 - $x^{4}$;                             (using (x+y)(x-y) identity)

Hence, this is our answer.

That's all.
