Find the sum of the three expressions and choose the correct answer.
-8a 3 b + 3a2 b 2 - 5
2 + 5a 2 b 2
3a 3 b + 7 - 9a 2 b 2
-5a3b - a2b2 + 2
-5a3b + 8a2b2 + 4
-5a3b - a2b2 + 4 **Weegy:** -8a^3b + 3a^2b^2 - 5 + (2 + 5a^2b^2) + (3a^3b + 7 - 9a^2b^2) = -8a^3b + 3a^3b + 3a^2b^2 + 5a^2b^2 - 9a^2b^2 - 5 + 2 + 7 = -5a^3b - a^2b^2 + 4 (More)
