then p(-2) ___________​

Answer 1

Pls mark as brainliest answer

Answer 2

GIVEN :-

$\implies \bf \: p(x) = x ^{3} - 2x + 2$

TO FIND :-

$\implies \bf \: The \: value \: of \: polynomial \: when \: p(-2)$

SOLUTION :-

$\to \rm \: p(x) = x ^{3} - 2x + 2 \\ \\ \to \rm \: p( - 2) = ( - 2) ^{3} - 2 \times ( - 2) + 2 \\ \\ \to \rm \: - 8 + 4 + 2 \\ \\ \to \rm \: - 8 + 6 \\ \\ \to \boxed{ \red{ \bf \: - 2}}$

Hence the required answer is (-2).
