Question

If p(x)=2Xɜ - 3X2 -5 find p (-1)​

Answer 1

$\huge\star\:\:{\orange{\underline{\pink{\mathbb{Solution}}}}}$

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

Answer 2

Answer:

$\huge\underbrace\mathfrak\pink{answer:-}$

If p(x)=2Xɜ - 3X2 -5 find p (-1)

p(-1)=2(-1)³-3(-1)²-5

=-2-3-5

p(-1)=-10
