Question

4) The GCD of (x-1), (x4-1) and (x2-1) is
b) x +1
a) x3-1
c) x+1
d) x-1​

Answer 1

Answer:

(d) x-1...............

Answer 2

Answer:

c) x+1

Step-by-step explanation:

GCD = Greatest Common Divisor.

x³−1=(x−1)(x²+xy+y2) {identity a³–b³and a²–b²}

x⁴ – 1 = (x² −1) (x²+1)

=(x−1)(x+1)(x²+1)

GCD=(x−1)
