Answer:
Step-by-step explanation:kx²+3x+3k
Use ∆=0
b²-4ac=0
(3)²-4(k)(3k)=0
9-12k²=0
-12k²=-9
k²=9/12
k=+or-3/√12

Answer:
Step-by-step explanation:
Given , the quadratic polynomial
kx² + 3k + 2x
= kx² + 2x + 3k
Here ,
a = k
b = 2
c = 3k
Now ,
And ,
Therefore , given that the sum of the zeroes is equal to the product of the zeroes, so :
