Q. 2 B4.6( 14 Votes )

# Find the value of k for each of the following quadratic equation, so that they have two equal roots.kx(x - 2) + 6 = 0

kx(x - 2) + 6 = 0

kx2 - 2kx + 6 = 0

If the quadratic Equation has equal root then their Discriminant = 0

4k2 - 4 × k × 6 = 0

k2 - 6k = 0

k(k - 6) = 0

k = 0,6

If k = 0 then the equation is no longer Quadratic
