3.1 Find roots (zeroes) of : F(x) = x4-2x3+78x2+166x+85Polynomial 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 integersThe 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 CoefficientIn this case, the Leading Coefficient is 1 and the Trailing Constant is 85. The factor(s) are: of the Leading Coefficient : 1 of the Trailing Constant : 1 ,5 ,17 ,85 Let us test ....
