Question 1012085: I have to factor the polynomial completely (a) over the real numbers, and (b) over the complex numbers.
X to the third power + 4x to the second power + 5x
I started with x(x squared +4x+5) i know that x=0 is a real root. But there are no real factors of 5 that add up to 4? So what do i do?
