Answer:
The first term is, 3x2 its coefficient is 3 .
The middle term is, -11x its coefficient is -11 .
The last term, "the constant", is +30
Step-1 : Multiply the coefficient of the first term by the constant 3 • 30 = 90
Step-2 : Find two factors of 90 whose sum equals the coefficient of the middle term, which is -11 .
-90 + -1 = -91
-45 + -2 = -47
-30 + -3 = -33
-18 + -5 = -23
-15 + -6 = -21
-10 + -9 = -19
For tidiness, printing of 18 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
