STEP

1

:

Equation at the end of step 1

(((7•(v2))-6v)-5)+((2v2-3v)+4)

STEP

2

:

Equation at the end of step

2

:

((7v2 - 6v) - 5) + (2v2 - 3v + 4)

STEP

3

:

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
