Question

Find the values of k for which the eqn x2-4x+k=0 has real and distinct real roots

Answer 1

Answer:

hey. A very easy question.  Even you can try your self . Just use the knowledge of quadratic formula.

Step-by-step explanation:

x² - 4x + k =0

here, a=1  b= -4  c =k

now given the roots are real and distinct,

b²-4ac > 0    [ D > 0   AND D = b²-4ac ]

16- 4k > 0   [ substituing the values of a , b ,c ]

16 > 4k

4k < 16

k < 4

This means that all values of k below 4 will give you real and distinct roots
