AB and AC are tangent to circle O. If AB measures 23 cm, what is the measure of AC?

(x) - (y) = (1 + 4i)

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

is there more to this question?
