Question

Find the value of K if the quadratic equation 3x2-k√3x+4=0 has equal roots

Answer 1

I hope this may help you......!

Answer 2

a=3,b=-K√3,c=4
D(discriminant)=
$b {}^{2} - 4ac$
putting values of a,b and c
$( - k \sqrt{3 { }^{} } ) {}^{2} - 4(3)(4) = 0\\ 3k {}^{2} - 48 = 0 \\ 3k {}^{2} = 48 \\ k {}^{2} = 16 \\ k = + 4 - 4$
