Question

Find the zero of the polynomial-
9x^2 - 1​

Answer 1

Answer:

9x2-1 = 0

(3x)2- 12=0

(3x-1)(3x+1)=0

x = 1/3 or -1/3

hopefully it will help you

Answer 2

Answer:

Step-by-step explanation:

Zero of the polynomial is also called its solution.

This means we have to find x

9x² - 1 = 0

9x² = 1

x² = 1/9

x = √1/√9              {∵√9 = 3}

x = 1/3 × √1

x = √1/3
