Two triangles are similar if they are the same, except one is bigger and one is smaller. Also, their angles are all the same. A career that uses similar triangles could be a mathematician, or a math teacher. Both of these need to be able to understand simple concepts like similar triangles to teach to their victims.
The cotangent function is defined as the ratio between cosine and sine of a given angle, i.e.

Since you can't have zero at the denominator, the cotangent function is not defined when the sine is zero.
Let's look at your option:
, so the cotangent is defined here
, so the cotangent is not defined here
, so the cotangent is defined here
, so the cotangent is defined here
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
