Question

factorize 1-x²

please answer fast...​

Answer 1

Step-by-step explanation:

x^2+1 cannot be factored in the reals. We can use the theory of quadratic discriminants to calculate b2−4ac=02−4(1)(1)=−4<0, hence x^2+1=0 has no real roots and thus cannot possibly be factored over the real numbers.

Answer 2

Answer:

1-x²

(1)²-(x)².

(1+x)(1-x).

Step-by-step explanation:

formula used

x²-y² = (x+y)(x-y)
