Answer
$p_{1}$ =1
$p_{2}$ =3
No, cubic polynomials must have at least one real zero.
Work Step by Step
The graph of $p_{1}$ shows the x axis being crossed only one time by the graph, so it only has one zero.
The graph of $p_{2}$ shows the x axis being crossed 3 times by the graph, so it has 3 zeros.
