Answer 1

Step-by-step explanation:

-3 and 0 this is your answer

Answer 2

Given:

A quadratic polynomial -3x²+k.

To find:

The sum of zeroes of the given quadratic polynomial.

Solution:

As we know that, in a quadratic polynomial ax²+ bx + k, the sum of zeroes of the quadratic polynomial is equal to the negative of the coefficient of x divided by the coefficient of x².

This means,

$sum \: of \: zeroes \: = \frac{ - b}{a}$

Now, as given,

We have a quadratic polynomial -3x²+k where a = -3 and b = 0. So,

The sum of zeroes of the quadratic polynomial -3x²+k is

$= \frac{ - b}{a} = \frac{ - (0)}{ - 3}$

$= 0$

Hence, the sum of zeroes of the given quadratic polynomial -3x²+k is 0.
