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

goog may have it for you

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
