Q. 2 A4.2( 5 Votes )

Find that value o

Answer :

Let us first solve the above equation,

kx2 – 2kx + 6 = 0


When we compare the above quadratic equation with the generalized one we get,


ax2 + bx + c = 0


a = k


b = -2k


c = 6


Since the quadratic equations have real and equal roots,


b2 – 4ac = 0 for real and equal roots


(-2k) 2 – (4 × k × 6) = 0


4k2 – 24k = 0


4k(k – 6) = 0


(k – 6) = 0 or 4k = 0


k = 6 or k = 0
