Hey there!

12 + 5a^2 - (15 - 3a^2)


DISTRIBUTE -1 WITHIN the PARENTHESES

= 12 + 5a^2 - 1(15) - 1(-3a^2)


= 12 + 5a^2 - 15 + 3a^2

COMBINE the LIKE TERMS

= (5a^2 - 3a^2) + (12 - 15)

= 5a^2 + 3a^2 + 12 - 15

= 8a^2 - 3


Therefore, your answer is: 8a^2 - 3


Good luck on your assignment & enjoy your day!
