Given a polynomial f(x), if (x + 2) is a factor, what else must be true

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

2/3(-6y+9x) expand each expression using the distributive property
