Step-by-step explanation:
8 + 2a + 3a + 5a = 8 + 10a
now we add up the 2 terms,
=> 7 - a - a² + 8 + 10a
=> 15 + 9a - a²
arrange the terms properly
=> -a² + 9a + 15

7 - a - a² from 8 + 2a + 3a+ 5a?
= 8 + 2a + 3a+ 5a - (7 - a - a² )
= 8 + 2a + 3a+ 5a - 7 + a + a²
= 8 - 7 + 2a +3a + 5a + a + a²
= 1 + 11a + a²
