Question

(x + 1)(x - 1) (x^2 + 1) = ?​

Answer 1

Answer:

Standard form:

x4 − 1 = 0

Factorization:

(x + 1)(x − 1)(x2 + 1) = 0

Solutions based on Jenkins–Traub algorithm:

x1 = −1

x2 = 1

x3 = −i

x4 = i

Extrema:

Min = (0, −1)

Answer 2

Explanation:

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

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

(x^4-1)

x^4-1

x^4=1

x=1
