Polynomial Question?

The graph of f(x) = ax^4+ bx^2 + cx -24 crosses the x-axis at 1,-2 and 3. Determine the equation of f(x).
 
How do I get an answer of f(x)=-4x^3 + 8x^2 + 20x - 24

Edward, you have ax4 in your problem and 4x3 in your answer.  Which is correct?

I dont't know. The answers say 4x^3 but the question says ax^4, unless there is a typo...
