4(x2143)
4*(x^214-3)

Step by Step Solution

Step  1  :

Equation at the end of step  1  :

  (22x213 • x) -  12

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   4x214 - 12  =   4 • (x214 - 3) 

Trying to factor as a Difference of Squares :

 3.2      Factoring:  x214 - 3 

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =
         A2 - AB + BA - B2 =
         A2 - AB + AB - B2 =
         A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 3 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

  4 • (x214 - 3)
