f(x)=x^3-10x^2+37x-52

**Anonymous**, Sunday, November 18, 2012 at 11:03pmfirst you need to graph on a graphing calculator to find a zero. once you do, you realize 4 is a zero so (x-4) is a solution. now you can either use long division or synthetic division. I chose synthetic.

4| 1 -10 37 -52

+4 -24 +52

= 1 -6 13 0

= x^2 -6x +13

then substitute that into the quadratic formula, find complex zeros

6 +/- the square root of -16 all over 2

simplifies to

3+4i or 3-4i
