Answer 2

Step-by-step explanation:

$\huge \green{ \bull} \: \underline \boldsymbol{ \pink{Solution:-}}$

By Reminder Theorem :

$\sf \: p(x) = {3x}^{2} + x + 7$

$\sf \: g(x) = x + 2$

$\sf \: g(x) = 0$

$\sf \blue{x + 2 = 0}$

$\sf \blue{x = - 2}$

now,

$\bf \gray{p( - 2) = 3 {x}^{2} + x + 7}$

$\bf \gray{p( - 2) = 3( - 2 {)}^{2} + ( - 2) + 7}$

$\bf \gray{p( - 2) = 12 - 2 + 7}$

$\bf \gray{p( - 2) = 17}$

$\boldsymbol {\therefore \: Remainder \: \: \: of p(x) = 3 {x}^{2} + x + 7 \: \: by \: \: x + 2. \: \: is \: \: 17 \: \: }$
