2x8(12x3+2x23x+1)
2x^8*(12x^3+2x^2-3x+1)

Step by Step Solution

Step  1  :

Equation at the end of step  1  :

  (((24•(x11))+(4•(x10)))-(6•(x9)))+2x8

Step  2  :

Equation at the end of step  2  :

  (((24•(x11))+(4•(x10)))-(2•3x9))+2x8

Step  3  :

Equation at the end of step  3  :

  (((24 • (x11)) +  22x10) -  (2•3x9)) +  2x8

Step  4  :

Equation at the end of step  4  :

  (((23•3x11) +  22x10) -  (2•3x9)) +  2x8

Step  5  :

Step  6  :

Pulling out like terms :

 6.1     Pull out like factors :

   24x11 + 4x10 - 6x9 + 2x8  = 

  2x8 • (12x3 + 2x2 - 3x + 1) 

Checking for a perfect cube :

 6.2    12x3 + 2x2 - 3x + 1  is not a perfect cube

Trying to factor by pulling out :

 6.3      Factoring:  12x3 + 2x2 - 3x + 1 

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

Group 1:  -3x + 1 
Group 2:  12x3 + 2x2 

Pull out from each group separately :

Group 1:   (-3x + 1) • (1) = (3x - 1) • (-1)
Group 2:   (6x + 1) • (2x2)

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 :

 6.4    Find roots (zeroes) of :       F(x) = 12x3 + 2x2 - 3x + 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  12  and the Trailing Constant is  1.

 
The factor(s) are:

of the Leading Coefficient :  1,2 ,3 ,4 ,6 ,12
 
of the Trailing Constant :  1

 
Let us test ....

  P  Q  P/Q  F(P/Q)   Divisor
     -1     1      -1.00      -6.00   
     -1     2      -0.50      1.50   
     -1     3      -0.33      1.78   
     -1     4      -0.25      1.69   
     -1     6      -0.17      1.50   
     -1     12      -0.08      1.26   
     1     1      1.00      12.00   
     1     2      0.50      1.50   
     1     3      0.33      0.67   
     1     4      0.25      0.56   
     1     6      0.17      0.61   
     1     12      0.08      0.77   


Polynomial Roots Calculator found no rational roots

Final result :

  2x8 • (12x3 + 2x2 - 3x + 1)
