(x ^ 4 - 3x ^ 3 + 5x - 6) * (x + 2) ^ - 1
divide polynomials using synthetic division

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
