Question

If the sum of the zeroes of the quadratic polynomial x? - kx +2 Is 3, then
find the value of k​

Answer 1

ANSWER

In a general quadratic equation of form ax²+bx+c=0, sum of roots are by -a/b

p(x) = 3x2 - kx + 6

sum of the zeroes = 3

= -(Cofficient of x)/(Cofficient of x2) 3

= -((-k)/3)

k = 9

Answer 2

Answer:

The value of k =3

Step-by-step explanation:

The given Polynomial is x²-kx+2 so, a=1,b= -k and c=2

and sum of its zeroes is 3= -b/a=k/1

=>k=3
