Answer 2

Answer:

Find roots (zeroes) of :       F(x) = x4-10x3+25x2-576

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  -576. 

 The factor(s) are: 

of the Leading Coefficient :  1

 of the Trailing Constant :  1 ,2 ,3 ,4 ,6 ,8 ,9 ,12 ,16 ,18 , etc
