Question

If the quadratic equation is x^2-2x+k has equal roots, than the value of k is

Answer 1

Answer:

K = 1

Step-by-step explanation:

Condition given is equal roots D = b²-4ac

Quadratic equation is x²-2x+k

A = 1 B = - 2 C = k

D = (-2)²-4(1)(k) =0

D = 4-4k =0

-4k = - 4 (shifting +4 to right hand side it becomes - 4)

K = 1
