Question

If the sum of the zeroes of the quadratic polynomial 3x^2 - kx+ 6 is 3, then find the valueof k
​

Answer 1

Answer:

let a and b be the zeros of the polynomial.

a+b= k/3

3= k/3

k= 9

Answer 2

Answer:

Step-by-step explanation:

$let \ p(x)=3x^2 - kx+ 6\\\\sum \ of \ zeros =-\frac{-k}{3} =\frac{k}{3} =3\\\\\bf k= 3\times 3=9$
