We are tasked to solve the value of p (8a) in the expression p (x) = 3x^2-4.

This means that what would find the value of the expression when x=8a. To solve this, we simply substitute the value of x in the expression.

p (x) = 3x^2-4

p (8a) = 3 (8a) ^2-4

p (8a) = 3 (64a^2) - 4

p (8a) = 192a^2-4
