w^2-13w+42=0

I get -6,-7 is this correct????

  • Math Help -

    yes it is, as:

    w^2-13w+42=0
    (w-7)(w-6)=0

  • Math Help -

    You correctly factored the trinomial, but that's not the solution.

    If (x-6)(x-7) = 0, then the equation is true only if one of the factors is zero.

    So, the solution is, x=6 or 7
