Answer 2

Answer:

 3x2 + 4x + 5

Step-by-step explanation:

STEP 1:  (3x2 +  4x) +  5

STEP 2:Factoring  3x2+4x+5  

The first term is,  3x2  its coefficient is  3 .

The middle term is,  +4x  its coefficient is  4 .

The last term, "the constant", is  +5  

Step-1 : Multiply the coefficient of the first term by the constant   3 • 5 = 15  

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   4 .

     -15    +    -1    =    -16  

     -5    +    -3    =    -8  

     -3    +    -5    =    -8  

     -1    +    -15    =    -16  

     1    +    15    =    16  

     3    +    5    =    8  

     5    +    3    =    8  

     15    +    1    =    16
