Answer:

5x²  - 7x + 3

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

 (5x²  -  7x) +  3

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  5x² -7x+3  

The first term is,  5x²   its coefficient is  5 .

The middle term is,  -7x  its coefficient is  -7 .

The last term, "the constant", is  +3  

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

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   -7 .

     -15    +    -1    =    -16  

     -5    +    -3    =    -8  

     -3    +    -5    =    -8  

     -1    +    -15    =    -16  

     1    +    15    =    16  

     3    +    5    =    8  

     5    +    3    =    8  

     15    +    1    =    16  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 5x²  - 7x + 3
