Question

Find value/values of k for which follwing quadratic equation has equal roots:x^2-2kx+k=0​

Answer 1

Answer:

k=0 or k=1

Step-by-step explanation:

for equal roots, discriminant has to be 0

so, 4k²-4k = 0

=> 4k(k-1)=0

so k=0 or k=1

therefore for k=0 or k=1, equation will have equal roots
