My math problem is 3n(squared) - 28 = -17n I have to factor this! So i would move the 17 over and make it 3n(squared) +17n - 28
wel
It's easier I think to take it and go "what can I add together than makes 17, yet multiplies to 28"
although, I don't think this is a perfect square, either

(x+7)(3x-4) = 0

heres the factored form, but I couldn't even begin to say how I got it, all I know is that it works
