Answer:

(m+9)  •  (m-2)

Step-by-step explanation:Step-1 : Multiply the coefficient of the first term by the constant   1 • -18 = -18  

Step-2 : Find two factors of  -18  whose sum equals the coefficient of the middle term, which is   7 .

     -18    +    1    =    -17  

     -9    +    2    =    -7  

     -6    +    3    =    -3  

     -3    +    6    =    3  

     -2    +    9    =    7    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  9  

                    m2 - 2m + 9m - 18

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

                   m • (m-2)

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

                   9 • (m-2)

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

                   (m+9)  •  (m-2)
