Q7. Verify whether x=1/√3,2/√3

are the zeros of p(x)=3x² - 1​

Answer 1

Step-by-step explanation:

1)x=1/root3

p(1/root3)=3(1/root3)^2-1

=3(1/3)-1=1-1=0

Because the answer is 0, therefore 1/root3 is the root

2)x=2/root3

p(2/root3)=3(2/root3)^2-1

=3(4/3)-1=4-1=3.

Because, it is not equal to 0, therefore this is not a zero.
