Taking this quickcheck right now..
Find all the zeros of each equation
x3 – x2 + 5x – 5 = 0
a) isqrt5, –isqrt5, 1
b) isqrt5, –isqrt5, –1
c) sqrt5,sqrt5, 1
d) isqrt5, 1
I suck at doing these. If you could show me the steps. I would appreiciate that.

Start by factoring: You'll get something like (x1)(x^2+5)=0 now solve each: (x1)=0 (x^2+5)=0... solve this one using the quadratic formula.

Start by solving the firt equation: (x1)=0 x1=0 x=1 now solve the second equation. (x^2+5)=0 x^2+5=0 subtract the 5 x^2=5 take the square root of both sides....(no need to really use the quadratic formula). x=sqrt5, x=(isqrt5), x=1

Oh ok I was confused on what the first step should be. So you factor first.. Ok. Thanks.
