Question

verify that 0and 3 are the zero of p (x) = x3-3x

Answer 1

Hey user !!

Here is your answer !!

____________________________________________⭐

For verification

Put value of the zeroes in

p(x)=x^3-3x

p(0) = (0)^3 -3(0)

= 0

Now,

p(x) = x^3 - 3x

p(3) = (3)^3 -3(3)

=27-9=18

so 3 is not a zero of polynomial

Hence verified

Hope it is satisfactory :-)

Answer 2

for verifying
we put x=0 in x3-3x
p(0) = (0)3. - 3×(0)
=0
we put x=3 in x3-3x
p(3) = (3)3 - 3×3
= 27-9=18
x=0 is the zero of p(x)
