 (1): "x2"   was replaced by   "x^2". 

Step  1  :

Equation at the end of step  1  :

  (3x2 -  19x) -  20

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  3x²-19x-20 

The first term is,  3x²  its coefficient is  3 .
The middle term is,  -19x  its coefficient is  -19 .
The last term, "the constant", is  -20 

Step-1 : Multiply the coefficient of the first term by the constant   3 • -20 = -60 

Step-2 : Find two factors of  -60  whose sum equals the coefficient of the middle term, which is   -19 .

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Final result :

  3x2 - 19x - 20
