Question

find the value of k for kx^2 - x - 6 if it have two different routes

Answer 1

since it has two different roots

Hence, Discriminant (D) = 0

Here a = k ,b = -1 ,c = -6

so,

D = 0

b²-4ac = 0

1 -4×k×(-6) = 0

1 + 24k = 0

24k = -1

k = -1/24 ..ans....

Answer 2

ANSWER :-

$<font color=red>$since it has two different roots

$<font color=dark pink>$

Hence, Discriminant (D) = 0

$<font color=green>$ Here a = k ,b = -1 ,c = -6

so,

$<font color=orange>$D = 0

b²-4ac = 0

1 -4×k×(-6) = 0

1 + 24k = 0

24k = -1

k = $\frac{-1}{24}$
