Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
2.1 Factoring 6x2-x-4
The first term is, 6x2 its coefficient is 6 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 6 • -4 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -1 .
