Question

The value(s) of k for which kx2 - 4x + 2 = 0 has real roots

Answer 1

Step-by-step explanation:

hello,

we have condition for real roots

b^2-4ac >= 0

=> 16-8k >= 0

=> 8k <= 16

so, k <= 2 ans.

Answer 2

Answer:

k=2

Step-by-step explanation:

d ques.is kx^2-4x+2=0

sol.

b^24ac=0 has equal n real roots

then

(-4)^2-4*k*2=0

16-8k=0

-8k=-16

k=2
