Question

value for k for quadratic equation 2x2-kx+k=0has equal roots is​

Answer 1

Answer:

Hello dear...❤️

Step-by-step explanation:

ok so here it goes..!!

Value(s) of

k

for which the quadratic equation

2x^2-kx+k=0

has equal roots is...

2x2−kx+k=0

ax2+bx+c=0

a=2, b= -k

c = k

For equal roots, the discriminant must be 0

D=b^2-4ac=0

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

k^2-8k=0

k(k-8)=0

hence, k=0,8...

hope this helps....

please mark me as branliest...
