$x=-3$, multiplicity 2, touches the x-axis and turns around; $x=\frac{5}{2}$, multiplicity 3, crosses the x-axis.
Based on the given equation, we can identify the zeros as: (i) $x=-3$ with a multiplicity of 2, which means that the graph will touch the x-axis and turn around at this zero (ii) $x=\frac{5}{2}$ with a multiplicity of 3, which means that the graph will cross the x-axis at this zero.
