Explanation:


\small{\underline{\tt{\red{Given}}}}


\rightarrow p(x) = -2


\small{\underline{\tt{\green{solution}}}}


\rightarrow
p(x) = 3x + {4x }^(2) - 5x + 8


\rightarrow
p( - 2) = 3( - 2) + 4( { - 2}^(2) ) - 5( - 2) + 8


\rightarrow
p( - 2) = - 6 + 16 + 10 + 8


\rightarrow
p( - 2) = 10 + 18


\rightarrow
p( - 2) = 28


\small\boxed{p(-2) = 28 }

Hope it helps
