Question

find if 1/2 is zero of 6x^2-3

Answer 1

Answer:

Quadratic Polynomial:

• A polynomial with degree 2 is called as a quadratic polynomial.
• It is in the form of ax^2 + bx + c.
• Example: 6x² + 11x - 35

Given:

The given quadratic polymial is 6x^2-3.

To Check:

We need to check whether 1/2 is the zero of 6x^2-3 or not.

Solution:

f(x) = 6x^2-3

Inorder to check whether 1/2 is the zero of 6x^2-3 or not, we need to substitute the value of x as 1/2.

Therefore, f(1/2) = 6 × (1/2)^2 - 3

=> 6 × 1/4 - 3

= 3 × 1/2 -3

=3/2 - 3

=( 3 - 6 )/2

= -3/2

Therefore-3/2 is not equal to zero, so 1/2 is not a zero of 6x^2-3.

Answer 2

Solutions:

f(x) = 6x² - 3

The value of x as 1/2.

6 × 1/4 - 3

3 × 1/2 - 3

3/2 - 3

(3 - 6)/2

-3/2
