Students were asked to write a trinomial that could not be factored using integers. which students followed the given directions.
pat x2 + 3x- 10
sam x2+x-12
mel x2+2x-1
lee x2+2x-3

ANSWER

Mel followed the right direction.

EXPLANATION

Pat's trinomial is;

There are factors of -10 that sums up to 3.

Hence this trinomial could be factored into (x-2)(x+5)

Sam's trinomial:

There are factors of -12 that sums up to 1.

4+-3=1

Mel's trinomial:

There are no factors of -1 that sums to 2.

This trinomial cannot be factored.

Lee's trinomial:

There are factors of -3 that sums up to 2

3+-1=2

sorry, i can't understand your question. will later if you describe more clearly!
