$\mathtt{\huge{\underline{\red{Answer\: :}}}}$

Question :

(b) x²-3x²y-4x+7 ,if x=-2 and y=2

To find :

The remainder in the answer =?

Given values :

x=-2 and y=2

$\huge\green{\sf{\underline{SOLUTION:}}}$

$\large \pink{ \bold{ \underline{step \: by \: step \: explaination}}}$

$\implies \displaystyle \sf \: {x}^{2} - 3 {x}^{2} y - 4x + 7$

$\: \large{ \red{ \bf{put \: the \: value \: of \: x \: and \: y \: in \: given \: equation}}}$

$\\ \hspace{3em} \implies \displaystyle \sf \: {( - 2)}^{2} - 3 {( - 2)}^{2} (2) - 4( - 2 ) + 7$

$\\ \hspace{3em} \implies \displaystyle \sf \: 4 - 3(8) + 8 + 7$

$\\ \hspace{3em}\implies \displaystyle \sf \: 4 - 24 + 8 + 7$

$\\ \hspace{3em}\implies \displaystyle \sf \: - 20 + 8 + 7$

$\\ \hspace{3em}\implies \displaystyle \sf \: - 12 + 7$

$\\ \hspace{3em}\implies \displaystyle \sf \: - 5$

$\green{\boxed{ \boxed{ \underline{ \color{gray} \bf{the \: answer \: will \: be \: - 5}}}}}$
