Write the zeros of the quadratic polynomial f(X) = 6x2 ‒ 3.

We know that,

To find the zeros of the quadratic polynomial we have to equate the f (x) to 0


f (x) = 0


6x2 – 3 = 0


3 (2x2 – 1) = 0


2x2 – 1 = 0


2x2 = 1


x2 = 1/2


x = � 1/√2


Hence, the zeros of the quadratic polynomial f (x) are 1/√2 and -1/√2
