Check whether 1,-3 are zeroes of the polynomial P(x)=x³-1 or not ?​

Answer 1

Answer:

1 is zero whereas -3 not zeros

MARK as BRAINLIEST please

Answer 2

Step-by-step explanation:

p(x) = x^3-1

=> Let x = 1

Putting the value of x in polynomial p(x):

p(x) = x^3-1

= 1^3-1

= 1-1

= 0

Hence, 1 is the zeros of polynomial p(x).

=> Let x = -3

Putting the value of x in polynomial p(x):

p(x) = x^3-1

= (-3)^3-1

= -27-1

= -28

Hence, -3 is not the zeros of polynomial p(x).
