How do you use the rational root theorem to find the roots of #2x^4 -7x^3 -35x^2 +13x +3#?
1 Answer
Use rational root theorem to find possible rational roots and try them to find rational roots
Then divide
Explanation:
Let
By the rational root theorem, any rational roots of
So the only possible rational roots are:
So
Use synthetic division to find:
The remaining quadratic factor
