Step-by-step explanation:
((2•3x2) - 11x) + 35 = 0
2.1 Factoring 6x2-11x+35
The first term is, 6x2 its coefficient is 6 .
The middle term is, -11x its coefficient is -11 .
The last term, "the constant", is +35
Step-1 : Multiply the coefficient of the first term by the constant 6 • 35 = 210
Step-2 : Find two factors of 210 whose sum equals the coefficient of the middle term, which is -11 .
-210 + -1 = -211
-105 + -2 = -107
-70 + -3 = -73
-42 + -5 = -47
-35 + -6 = -41
-30 + -7 = -37
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
