Answer:

Factoring  x2+5x-414 

The first term is,  x2  its coefficient is  1 .

The middle term is,  +5x  its coefficient is  5 .

The last term, "the constant", is  -414 

Step-1 : Multiply the coefficient of the first term by the constant  1 • -414 = -414 

Step-2 : Find two factors of  -414  whose sum equals the coefficient of the middle term, which is   5 .

     -414   +   1   =   -413     -207   +   2   =   -205     -138   +   3   =   -135     -69   +   6   =   -63     -46   +   9   =   -37     -23   +   18   =   -5     -18   +   23   =   5   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -18  and  23 

                     x2 - 18x + 23x - 414

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

                    x • (x-18)

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

                    23 • (x-18)

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

                    (x+23)  •  (x-18)

             Which is the desired factorization
