"Calculate the discriminant and use it to tell whether or not the trinomial factors. Factor those that do."

x^2-10x+74

I found the discriminant (-196) and that is a perfect square, so the equation should factor, right? I can't figure out how to though. What am I doing wrong?

if you want to factor the above equation, u need to find 2 numbers that would give you 74 when multiplied and that gives you -10 when added

ajoy31 · Answer

factors of 74 are 1x74 and 2x34, none of those add to (-10)
