Question

Values of k for which the quadratic equation 2x2 – kx + k = 0 has equal roots is

Answer 1

Answer:

$Value \:of \: k = 0 \:or\:8$

Step-by-step explanation:

Compare given Quadratic equation 2x²-kx+k=0 with ax²+bx+c=0, we get

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

Discreminant (D)=0

[ Given roots are equal ]

=> b²-4ac=0

=> (-k)²-4×2×k=0

=> k²-8k=0

=> k(k-8)=0

=> k = 0 or k=8

Therefore,

$Value \:of \: k = 0 \:or\:8$
