Step 1: First we have to write polynomials in descending order.
$$ \begin{aligned} P(x) &= -2 \\ Q(x) &= 3v-3 \\ \end{aligned} $$We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \color{blue}{-2} \cdot \left( 3v-3 \right) &= \color{blue}{-2} \cdot 3v + \color{blue}{-2} \cdot \left( -3\right) = \\ &= -6v+6 \end{aligned} $$
