Question

Find the least common multiple of x^3 - x^2 + x - 1 and x^2 - 1. In factored form.

A. (x + 1)^2(x - 1)
B. (x + 1)(x - 1)(x^2 + 1)
C. (x^3 - x^2 + x - 1)(x^2 - 1)
D. (x + 1)(x - 1)(x^2 - 1)

Answer 1

LCM = C. (x^3 - x^2 + x - 1)(x^2 - 1)

It's like if you were looking for the LCM of two numbers a and b, you would do a*b :)

Answer 2

thank you

Answer 3

never a problem! :D
