Question

If the sum of the zeroes of the quadratic polynomial 3x2

-kx+6 is 3, then find

the value of k.​

Answer 1

Answer:

Polynomial is $3x^{2} -kx+6$

Sum of Zeroes , a+b = $\frac{-b}{a}$

So, $\frac{-(-k)}{3}=3$

As it is given in question that sum is 3

So from the above equation,

k = 3*3

k = 9
