Question 419768
A "coefficient" of a variable is the multiplier within the term that contains the variable.  In the equation:

{{{-12q^2 - q + 11}}} the term that contains the variable {{{q^2}}} is the term {{{-12q^2}}}.  The "multiplier" of {{{q^2}}} is -12.  Therefore, the coefficient of {{{q^2}}} in the expression {{{-12q^2 - q + 11}}} is -12.
