$\huge \bf \color{aqua}Answer$

• Let p(x) = 7 - 2x - 3x² ,
• g(x) = 2x² - 5x - 3

According to the question

$\sf \: p(x) - g(x)$

$\sf \pink⇨( 7 - 2x - 3x² ) - ( 2x² - 5x - 3 )$

$\sf \red⇨7 - 2x - 3x² - 2x² + 5x + 3$

$\sf \green⇨-3x² - 2x² - 2x + 5x + 7 + 3$

$\sf \color{maroon}{⇨}- 5x² + 3x + 10$
