Polynomial Roots Calculator :

3.1 Find roots (zeroes) of : F(b) = 4b3-6b2+1

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

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers b 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 4 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1,2 ,4

of the Trailing Constant : 1
