for what are value of k are the roots of 3x^2-6x+k=0 equal?

  • algebra2/trig -

    For the roots of the quadratic equation
    ax^2+bx+c=0
    to be equal, the discriminant Δ must equal to zero, where
    Δ=b^2-4ac...(1)

    For the given equation
    3x^2-6x+k=0
    a=3,b=-6, c=k
    Substitute a,b,and c in (1), equate to zero and solve for k.

    Post your answer for checking if you wish.
