Does anybody know this question?

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?
