Question

Find the sum of the three expressions and choose the correct answer. -8a^3b + 3a^2b^2 - 5 2 + 5a^2b^2 3a^3b + 7 - 9a^2b^2 A -5 a3b - a2b2 + 2 B -5 a3b - a2b2 + 4 C -5 a3b + 8 a2b2 + 4

Answer 1

B. -5a³b-a²b²+4

Explanation:

-8a³b+3a²b²-5

2+5a²b²

3a³b+7-9a²b²

-8a³b+3a²b²-5+2+5a²b²+3a³b+7-9a²b²=

-5a³b+3a²b²-5+2+5a²b²+7-9a²b²=

-5a³b-a²b²-5+2+7=

-5a³b-a²b²+4

The option that fits this best is B.

A. -5a³b-a²b²+2

B. -5a³b-a²b²+4

C. -5a³b+8a²b²+4
