Hey Elizabeth -- if 2x^3 -9x^2

**-2x**+3, then 1/2 is a root ... divide by 2x-1 to get quadratic :)Are you sure your coefficients are correct?

This polynomial does not factor in an obvious way. The exact solution requires use of the so-called cubic formula, which involves complex numbers. The three roots are irrational numbers and can be approximated numerically. You get

x

_{1}≈-0.458, x_{2}≈0.784, x_{3}≈4.174
