Question

if the roots of the equation x2-xplus k=0 are real and equal, then the value of k is

Answer 1

Answer:

k = 1/4

Step-by-step explanation:

Since the roots of the equation are real and equal then,

D = b² - 4ac = 0

{where a, b, c have there usual meaning}

(-1)² - 4(1)(k) = 0

1 - 4k = 0

k = 1/4
