The first term is, x2 its coefficient is 1 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -3000
Step-1 : Multiply the coefficient of the first term by the constant 1 • -3000 = -3000
Step-2 : Find two factors of -3000 whose sum equals the coefficient of the middle term, which is 5 .
-3000 + 1 = -2999
-1500 + 2 = -1498
-1000 + 3 = -997
-750 + 4 = -746
-600 + 5 = -595
-500 + 6 = -494
For tidiness, printing of 26 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
