Answer:

[tex]-3 - 2x + 3x^2[/tex]

Step-by-step explanation:

The question looks incomplete; However, it can be answered based on the available data

Given

[tex](3 - 4x + 8x^2) + (-6 + 2x - 5x^2)[/tex]

Required

Add

Step 1: Rewrite without bracket

[tex]3 - 4x + 8x^2 - 6 + 2x - 5x^2[/tex]

Step 2: Arrange in descending order

[tex]3 - 6 - 4x + 2x + 8x^2 - 5x^2[/tex]

Step 3: Perform Arithmetic Operations

[tex]-3 - 2x + 3x^2[/tex]

The expression cannot be simplified any further;

Hence, the addition of [tex](3 - 4x + 8x^2) + (-6 + 2x - 5x^2)[/tex] is equivalent to [tex]-3 - 2x + 3x^2[/tex]
