factor.
x^2  4x + 40 = 0.
i'm having some trouble with this one, so please help! thanks!

not every quadrtic trinomial factors, you have one that doesn't
for yours to factor you would need two integers, so that when you multiply them you would get 40 and when you add them you would get 4.
not very likely, so no factors.
