Try this:

-3%28p-7%29%3E21
-3%28p-7%29-21%3E0
-3p%2B21-21%3E0
-3p%3E0

Critical value for p is 0.
-3%2A0=0 but you want left member -3p to be GREATER THAN 0.
Negative multiplied by negative will be POSITIVE meaning greater than 0.

%28-3p%29%28-1%2F3%29%3C0%2A%28-1%2F3%29, and notice carefully the Order change;
