Write the equation p(x)=2x^4+9x^3+17x^2+19x-15 in factored form
-----------
I graphed it and found zeroes at x = -3 and x = 1/2
---
So it has factors (x+3) and (2x-1)
---
The other factors are complex numbers that you can find
using synthetic division.
Divide by x+3
Then divide by x-(1/2)
---
Then you have a quadratic quotient.
So use the Quadratic Formula to find
the complex roots.
