Question

If the quadratic equation isx^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)

D = 4-4k = 0

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

K = 1
