What are the zeros of the quadratic function f(x)=2x^2-10x-3

The zeros of the  quadratic function are:

Zeros of a function are the possible x values of the function for which the function is equal to zero.

i.e.  all those x for which  f(x)=0

We are given a function f(x) by:

Now, f(x)=0

We know that the solution of the quadratic equation of the type:

        is given by:

Here we have:

a=2, b= -10 and c= -3

Hence, the solution is:

Hence,

and

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
