Step-by-step explanation:

First, they want you to draw an arc centered at the vertex A. It will intersect the lines at two points. One point is B and the other is C.

Next, they want you to draw two more arcs, one at B and one at C. The two arcs must have the same radius. They intersect at point X.

Draw a line from A to X. That's the angle bisector.

Replace f(x) with 0 and swith the equation around to solve for x

x^4 - 32x^2 - 144 = 0

Factor the left side:

(x+6) (x-6) (x^2+4)

so far we have x+6 = 0, x = -6
x -6 = 0, x = 6

solve x^2 +4 = 0
x^2 = -4
x = sqrt(-4)
x = 2i, -21

The answer is B) 2i, 6, -6

Semiannual means there will be two total periods in a year. Divide ten percent by two to get the interest rate per period. Then multiple by 1+i twice
