Recall that to evaluate an expression at some given values, we substitute each variable with the corresponding given value.
Evaluating 2c²d-3cd at c=-1 and d=-2 we get:
[tex]2(-1)^2(-2)-3(-1)(-2).[/tex]Simplifying the above result we get:
[tex]\begin{gathered} 2(1)(-2)-3(-1)(-2), \\ -4-6, \\ -10. \end{gathered}[/tex]Answer: Option a.
