The quadratic equation x^2 + 4kx+2(k+1) = 0 has equal roots, find the possible values of k.

For a quadratic equation ax^2 +bx +c = 0 with equal roots we know the discriminant b^2-4ac must equal 0. From our equation we have a=1, b=4k and c=2(k+1) so using b^2-4ac = 0 we have (4k)^2 -4 1 2(k+1) = 0 E...
