Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, +30x its coefficient is 30 .
The last term, "the constant", is -162000
Step-1 : Multiply the coefficient of the first term by the constant 1 • -162000 = -162000
Step-2 : Find two factors of -162000 whose sum equals the coefficient of the middle term, which is 30 .
-162000 + 1 = -161999
-81000 + 2 = -80998
-54000 + 3 = -53997
-40500 + 4 = -40496
-32400 + 5 = -32395
-27000 + 6 = -26994
For tidiness, printing of 94 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
