Simplify the following rational expression. List all of the excluded values, and classify each as a removable discontinuity, or a nonremovable discontinuity.
-2/x^2-4 + x-1/x^2-2x

This one is really hard. Make sure to follow the steps exactly!

Since both are like rational compounds, add them together: (x-3)/(2x^2-2x -4)

Factor out GCF from denomination: (x-3)/ 2(x^2-x-2)

Factor the denom: (x-2)/2(x-2)(x-1)

Restrctions: x = 2 and 1. These are removeable because they make the denom  = .0

Cancel the x-2 factorials: 1/2(x-1).

Final 1/2(x-1), removeable discontinuations are 2 and 1. Nonremovable is just y = 1/2 or .5 since that is the stretch factor.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
