Question

check whether 3 and -3 are the zeroes of x³-27​

Answer 1

Answer:

-3 is zero of - 27, hope it will help you

Answer 2

Question: Check whether 3 and -3 are zeros of polynomial x³ - 27.

Solution: For 3,

p(x)= x³ - 27

p(3)= (3)³ - 27

= ( 3×3×3) - 27

= 27 - 27

= 0

For ‘ -3 '

p(x)= x³ - 27

p(-3)= (-3)³ - 27

= (-3×-3×-3) - 27

= -27 - 27

= -54

•°• From the above equation we got that 3 is a zeros of polynomial x³-27 and ‘-3’ is not a zeros of polynomial x³-27.
