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
