Question

The LCM of two polynomials x + 1 and x4 - 1 is?

Answer 1

Answer:

(x²+1)(x-1)

Step-by-step explanation:

1st expression=x+1

2nd expression=x⁴-1

=(x)⁴-(1)⁴

=(x²)²-(1²)²

=(x²-1)(x²+1)

=[(x-1)(x+1)] (x+1)²-2x

=(x+1)[(x-1)(x+1)-2x]

now,

LCM=(x+1)(x-1)(x+1)-2x

=(x+1)²(x-1)-2x

=(x²+1)(x-1)
