Question

(3-4x+8x^2)+(-6+2x-5x^2)

Answer 1

To simplify the expression \((3 - 4x + 8x^2) + (-6 + 2x - 5x^2)\), we can combine like terms.

1. Combine the constant terms:
\(3 - 6 = -3\)

2. Combine the \(x\) terms:
\(-4x + 2x = -2x\)

3. Combine the \(x^2\) terms:
\(8x^2 - 5x^2 = 3x^2\)

Now, putting it all together, we have:

\[
3 - 6 = -3
\]
\[
-4x + 2x = -2x
\]
\[
8x^2 - 5x^2 = 3x^2
\]

So, the simplified expression is:

\[
3x^2 - 2x - 3
\]

Thus, the final result is:

\[
3x^2 - 2x - 3
\]
