Trying to factor by splitting the middle term
3.1 Factoring 9v2-9v-1
The first term is, 9v2 its coefficient is 9 .
The middle term is, -9v its coefficient is -9 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 9 • -1 = -9
Step-2 : Find two factors of -9 whose sum equals the coefficient of the middle term, which is -9 .
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
