  • I'm probably going to find this out tomorrow morning, but I need to find a polynomial function with two complex numbers... I got one by some educated guessing that might not even be right, but i'm having a problem with a two degree polynomial that has the zeros of i and 1-2i... did you answer it here and I just didnt understand, or is this something else entirely?

  • You just explained more to me than my college algebra teacher has in a 50 minute class 3

  • @tanquantwal You're welcome. Glad i could help :)

  • @TheAncientEmperor Thank You. I never understood it fully.

  • @tanquantwal notice that in front of the parenthesis is a minus sign -(6+8i) so he changed signs from -(6+8i) to -6-8i

  • thanks mr J sucks dick

  • youre the man, seriously youre awesome men, becuas you use you time to make these videos for us, if you ever come to mexico, youre a genius too, if you ever come to mexico ill buy you a beer men or anything you like haha

  • Dickbutt

  • This is so helpful. But in the add/sub can you please tell me why you changed (6+8i) to 6-8i ? Why did you change the positive to a negative when you bought the number down out of the parenthesis?

  • should get youtube partnership and make money.
