Ok... I am soooooo lost with this.
I need to factor out to find zeros of an equation.
–x4 + 10x2 + 8x – 8 is the equation.
I don't understand.... AT ALL... how they factored out the (x + 2) to get this:
(x + 2)( )
I understand "factoring out" something, but I don't understand how to factor out say... x+2
Thanks guys... this is really bothering me, and I have a test tomorrow. Definitely need to understand this concept.
