Factoring  x2+9x-22  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +9x  its coefficient is  9 .

The last term, "the constant", is  -22  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -22 = -22  

Step-2 : Find two factors of  -22  whose sum equals the coefficient of the middle term, which is   9 .

     -22    +    1    =    -21  

     -11    +    2    =    -9  

     -2    +    11    =    9    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  11  

                    x2 - 2x + 11x - 22

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

                   X • (x-2)

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

                   11 • (x-2)

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

                   (x+11)  •  (x-2)

            Which is the desired factorization
