Answer 1

$\small\blue{\sf{\bold{Question:}}}$

• $\small\sf{x}^{2}\:{-\:3\:(x\:+\:3)\:=\:0}$

$\small\blue{\sf{\bold{Solution:}}}$

$\small{↠}$$\small\sf{x}^{2}\:{-\:3\:(x\:+\:3)}$

$\small{↠}$$\small\sf{x}^{2}\:{-\:3x\:+\:9}$

$\small{↠}$$\small\sf{x}^{2}\:{-\:3x\:-\:3x\:+\:9}$

$\small{↠}$$\small\sf{x\:(x\:-\:3)\:-3\:(x\:-\:3)}$

$\small{↠}$$\small\sf{x\:-3\:;\:x\:-\:3}$

• $\small\sf{\boxed{\bold{\orange{x\:=3\:\:||\:\:{x\:=3}}}}}$
