(7x2+2)(2x1)
(7x^2+2)*(2x-1)

Step by Step Solution

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

Step  1  :

Equation at the end of step  1  :

  (((14 • (x3)) -  7x2) +  4x) -  2

Step  2  :

Equation at the end of step  2  :

  (((2•7x3) -  7x2) +  4x) -  2

Step  3  :

Checking for a perfect cube :

 3.1    14x3-7x2+4x-2  is not a perfect cube

Trying to factor by pulling out :

 3.2      Factoring:  14x3-7x2+4x-2 

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

Group 1:  4x-2 
Group 2:  14x3-7x2 

Pull out from each group separately :

Group 1:   (2x-1) • (2)
Group 2:   (2x-1) • (7x2)
               -------------------
Add up the two groups :
               (2x-1)  •  (7x2+2) 
Which is the desired factorization

Polynomial Roots Calculator :

 3.3    Find roots (zeroes) of :       F(x) = 7x2+2
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  7  and the Trailing Constant is  2.

 
The factor(s) are:

of the Leading Coefficient :  1,7
 
of the Trailing Constant :  1 ,2

 
Let us test ....

  P  Q  P/Q  F(P/Q)   Divisor
     -1     1      -1.00      9.00   
     -1     7      -0.14      2.14   
     -2     1      -2.00      30.00   
     -2     7      -0.29      2.57   
     1     1      1.00      9.00   
     1     7      0.14      2.14   
     2     1      2.00      30.00   
     2     7      0.29      2.57   


Polynomial Roots Calculator found no rational roots

Final result :

  (7x2 + 2) • (2x - 1)
