DochEvi [55]

Answer:

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   2 • 2 = 4  

Step-2 : Find two factors of  4  whose sum equals the coefficient of the middle term, which is   3 .

     -4    +    -1    =    -5  

     -2    +    -2    =    -4  

     -1    +    -4    =    -5  

     1    +    4    =    5  

     2    +    2    =    4  

     4    +    1    =    5  

Observation : No two such factors can be found !!
