-1/3 is a zero of 3x + 1. Is the given statement true or false

Solution:

Given, -1/3 is a zero of 3x + 1.

We have to determine if the given statement is true or false.

For some values of the variable the polynomial will be equal to zero. These values are called zeros of polynomial.

Given, the polynomial is 3x + 1

Let f(x) = 3x + 1

To find zero of polynomial,

f(x) = 0

3x + 1 = 0

3x = -1

So, x = -1/3

Therefore, the zero of the polynomial is -1/3.

✦ Try This: Verify whether the following is True or False : -4 is a zero of x - 4.

Given, -4 is a zero of x - 4.

We have to determine if the given statement is true or false.

For some values of the variable the polynomial will be equal to zero. These values are called zeros of polynomial.

Given, the polynomial is x - 4

Let f(x) = x - 4

To find zero of polynomial,

f(x) = 0

x - 4 = 0

So, x = 4

Therefore, the given statement “-4 is a zero of x - 4” is false.
