Question

If sum of the zeroes of the quadratic polynomial 3x? - kx + 6 is 3, then find
the value of k
a) 3
b) 9
O O O O
c) 6
O d) none of these​

Answer 1

Answer:

let the zeroes of polynomial be a and b

sum of zeroes = a+b=3

3=k/3

k= 9

Step-by-step explanation:

hope it helps

Answer 2

Step-by-step explanation:

Sum of zeroes of quadratic polynomial = - b/a = - (-k) /3 = 3(given)

=>k/3 =3

=>k = 9
