Question

verify whether the following are zeros of the polynomial, indicated against them.
1) p(x) = 3x2 - 1 where X= -1/root 3, 2/root 3.
step by step​

Answer 1

Answer:

p(x) = 3x^2 -1

on putting x= -1/root3

p(-1/root 3)= 3×(-1/root 3)^2-1 = 3×1/3-1 = 0

Therefore, x= 1/root3 is the zeros of p(x).
