Polynomial Roots Calculator :

 6.2    Find roots (zeroes) of :       F(x) = 9x3 - 17x2 + 7
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  9  and the Trailing Constant is  7.

 
The factor(s) are:

of the Leading Coefficient :  1,3 ,9
 
of the Trailing Constant :  1 ,7

 
Let us test ....

  P  Q  P/Q  F(P/Q)   Divisor
     -1     1      -1.00      -19.00   
     -1     3      -0.33      4.78   
     -1     9      -0.11      6.78   
     -7     1      -7.00     -3913.00   
     -7     3      -2.33      -199.89   
     -7     9      -0.78      -7.52   
     1     1      1.00      -1.00   
     1     3      0.33      5.44   
     1     9      0.11      6.80   
     7     1      7.00      2261.00   
     7     3      2.33      28.78   
     7     9      0.78      0.95   


Polynomial Roots Calculator found no rational roots

Final result :
