Question

Find the common zero of x2

- 1, x4

-1 and (x+1)2

.​

Answer 1

Answer:

x = -1 is the common zero of the given polynomials

Step-by-step explanation:

x2 -1 can be written as( x+1)(x-1)

x4 -1 can be written as (x+1)(x-1)(x2+1)

(x+1)2 can be written as (x+1)(x+1)

from these we can observe that (x+1) is the common factor of the given polynomials

thus for common zero,

x+1=0

thus ,x=. -1,will be the common zero
