Question

6. Find the value of k so that the quadratic equation kx2 - 2kx + 6 = 0 have two equal roots.​

Answer 1

Answer:

Value of k = 0 Or k=6

Step-by-step explanation:

Answer:

Value of k = 0 Or k=6

Step-by-step explanation:

Given Quadratic equation:

kx?-2kx+6=0 has equal roots.

Compare above equation with

ax?+bx+c=0 we get

a=k, b = -2k, c = 6

Now

Discreminant (D)=0

given roots are equal ; therefore

b2-4ac=0

=> (-2k)*-4x(k)x6 = 0

=> 4k?-24k=0

=> 4k(K-6)=0

=> 4k=0 Or k-630

=> k=0 Or k=6

Therefore,

Value of k = 0 Or k=6
