Polynomial Roots Calculator :

2.1 Find roots (ZEROES) of : F(x) = x4-2x3-x2-2x+1

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots TEST is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the QUOTIENT of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1

of the Trailing Constant : 1

Let us test ....
