Answer 1

$\large{\underline{\underline{\boxed{\sf{\purple{Answer}}}}}}$

${ \mathtt{\blue{0 - (2a {}^{3} + 5a {}^{2} + 3a + 7) }}} \\ { \mathtt{\blue{0 - 2a {}^{3} - 5a {}^{2} - 3a - 7 }}} \\ { \mathtt{\blue{ - 2 a {}^{3} - 5a {}^{2} - 3a - 7}}}$

Answer 2

subtract 2a³ + 5a² + 3a + 7 from 0

This equation, crossing from big to small

0

- (2a³ + 5a² + 3a + 7)

= -2a³ - 5a² - 3a - 7
