Question

. If the sum of the zeroes of the quadratic polynomial is kx2+2x+3k is equal to the product of its zeros, then k=?​

Answer 1

Answer:

k is -2/3

given polynomial = kx2−2x−3k 

if ax2+bx+c is a polynomial then its sum of roots is given by a−b and product of roots is given by ac 

∴ sum of roots of given polynomial =k−(−2)=k2 

product of roots =k−3k=−3

 

it is given that sum of roots = product of roots 

k2=−3 

k=3−2

Answer 2

Step-by-step explanation:

a+b = ab

a+b = -b/a

ab= c/a

-2/k = 3/k
