Take a sample point and draw.

#### Explanation:

get a sample point of

draw a curve connecting each line.

Since there are only function of

the graph is symmetry to polar axis.

graph{((x^2)+(y^2))^2=4(x^3+y^2+x*(y^2)) [-10, 10, -5, 5]}

These type of graph is called Limaçon.

general form is

The shape depends on the relationship between a and b.

In this case a=b
