$\: \bf{the \: value \: of \: the \: polynomial \: 5 {x}^{2} + 9 \: when \: x = - 1 \: is}$

$\: \large\ggg \green{ \bf{5 {x}^{2} + 9}}$

$\: \large \ggg \green{ \bf{5( {( -1))}^{2} + 9}}$

$\: \: \ggg \large \green{\bf{5 + 9}}$

$\: \: \large \ggg \green{ \bf{14}}$

$\: \: \bullet \large \boxed{\orange{ \underline{ \bold{14 \: is \: the \: answer}}}}$
