Question

If p(x)=2Xɜ - 3X2 -5 find p (-1)

Answer 1

$\Large \underline{ \underline{ \bf \green{Given :}}}$

$\longrightarrow \: \sf p(x) = {2x}^{3} - {3x}^{2} - 5$

$\Large \underline{ \underline{ \bf \green{To \: Find :}}}$

$\longrightarrow \: \sf \: value \: of \: p( - 1)$

$\Large \underline{ \underline{ \bf \green{Solution :}}}$

$\longrightarrow \: \sf p(x) = {2x}^{3} - {3x}^{2} - 5 \\ \\ \longrightarrow \: \sf p( - 1) = 2 {( - 1)}^{3} - 3 {( - 1)}^{2} - 5 \\ \\ \longrightarrow \: \sf p( - 1) = 2( - 1) - 3(1) - 5 \\ \\ \longrightarrow \: \sf p( - 1) - 2 - 3 - 5 \\ \\ \longrightarrow \: \sf p( - 1) = - 10$
