Checking for a perfect cube :

3.1    3x4 + 2x2 - 6x + 1  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  3x4 + 2x2 - 6x + 1  

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -6x + 1  

Group 2:  3x4 + 2x2  

Pull out from each group separately :

Group 1:   (-6x + 1) • (1) = (6x - 1) • (-1)

Group 2:   (3x2 + 2) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

3.3    Find roots (zeroes) of :       F(x) = 3x4 + 2x2 - 6x + 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  3  and the Trailing Constant is  1.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1

Let us test

 P    Q    P/Q    F(P/Q)    Divisor

     -1       1        -1.00        12.00      

     -1       3        -0.33        3.26      

     1       1        1.00        0.00      x - 1  

     1       3        0.33        -0.74      

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

  3x4 + 2x2 - 6x + 1  

can be divided with  x - 1
