Question

of the following:-
1. (5a3 + 6a+ + 3a2 - 9 + 5a) + (a2-1)
2. (24m - 10m2 + m) + (m + 4)​

Answer 1

Answer:

1. 5a3 + 4a2 + 11a - 10

2. -10m2 + 26m + 4

Step-by-step explanation:

1. (5a3 + 6a+ + 3a2 - 9 + 5a) + (a2-1)

= 5a3 + 6a + 3a2 - 9 + 5a + a2 - 1

= 5a3 + 3a2 + a2 + 6a + 5a - 9 - 1

= 5a3 + 4a2 + 11a - 10

2. (24m - 10m2 + m) + (m + 4)

= 24m - 10m2 + m + m + 4

= -10m2 + 24m + m + m + 4

= -10m2 + 26m + 4
