Question

The quadratic equation x^2 - 4x + k = 0 has distinct real roots if

Answer 1

Answer:

k< 4

Step-by-step explanation:

x² - 4x + k = 0

Find the discriminant:

D = b² - 4ac

D = (-4)² - 4(1)(k)

D = 16 - 4k

The roots are real and distinct:

D > 0

16 - 4k > 0

-4k > -16

4k < 16

k < 4

Answer: k < 4
