Question

prove that x+1 is a factor of x^99+1 and x^100-1 show full calculations

Answer 1

Answer:

Step-by-step explanation:

If x + 1 is a factor, then x= -1 should satisfy the equations.

1) x^99 + 1 = 0

Put x  = - 1  

-1 -1 = -2

So, it is not a factor

2) x^100 - 1

Put x = - 1

1-1 = 0

So, it is a factor
