Answer:
=14a^2+2a-12
Step-by-step explanation:
The sum of: (8a-6a^2+9)and( -10a-(+8a^2))
=(8a-6a^2+9)+(-10a-8a^2) ..... ( - + = -)
=8a-6a^2+9-10a-8a^2 ......
( sign in the second () does not change )
=-6a^2-8a^2+8a-10a+9
=-14a^2-2a+9 ....... (1)
Subtract (1) from -3:
=(-3)-(-14a^2-2a+9)
=-3+14a^2+2a-9
( sign in the second () changes)
=+14a^2+2a-9-3
=14a^2+2a-12
