Explanation:
To determine p(c), substitute x = c into p(x).
rArr p(color(red)(c))=4(color(red)(c))^2-33(color(red)(c))-180⇒p(c)=4(c)2−33(c)−180 Thus
p(c)=4c^2-33c-180p(c)=4c2−33c−180 Similarly to evaluate p(c) when c = 12, substitute c = 12 into p(c)
rArr p(color(red)(12))=4(color(red)(12))^2-33(color(red)(12))-180⇒p(12)=4(12)2−33(12)−180 Hence
p(12)=(4xx144)-(33xx12)-180=0p(12)=(4×144)−(33×12)−180=0
