Question

Find the sum and the product of the roots is the quadratic equation
kx²-k²x-2k³=0​

Answer 1

Step-by-step explanation:

Quadratic equation has equal roots then b

2

−4ac=0

Given that kx

2

−2kx+6=0

Here a=k,b=−2k and c=6

Now, (−2k)

2

−4×k×6=0

⇒4k

2

−24k=0

⇒4k(k−6)=0

⇒k=0 or k=6
