STEP

1

:

Equation at the end of step 1

 ((a4) -  3a2) +  2

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  a4-3a2+2  

The first term is,  a4  its coefficient is  1 .

The middle term is,  -3a2  its coefficient is  -3 .

The last term, "the constant", is  +2  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 2 = 2  

Step-2 : Find two factors of  2  whose sum equals the coefficient of the middle term, which is   -3 .

     -2    +    -1    =    -3    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  -1  

                    a4 - 2a2 - 1a2 - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   a2 • (a2-2)

             Add up the last 2 terms, pulling out common factors :

                    1 • (a2-2)

Step-5 : Add up the four terms of step 4 :

                   (a2-1)  •  (a2-2)

            Which is the desired factorization
