P(x) = 2x^3 − 14x^2 + 15x − 18
Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! P(x) = 2x^3 − 14x^2 + 15x − 18
-------------
Look for a real zero - a factor of 18.
1, 2, 3, 6, 9 or 18 Plus and minus.
If you have Excel, you can use that to try the factors.
----
If there is one, Divide the cubic by (x - factor).
That will leave a quadratic.
