To simplify the expression \(5x^3 - 8x^2 + 34x^2\), we first need to combine like terms.
The term \( -8x^2\) and \( +34x^2\) can be combined:
\[
-8x^2 + 34x^2 = 26x^2
\]
So the expression simplifies to:
\[
5x^3 + 26x^2
\]
Next, this can be factored to identify common factors if possible:
\[
x^2(5x + 26)
\]
Now, let’s compare this with the provided answer options:
- \( \frac{5x^5}{4} - 2x^4 + \frac{3}{4}x^2 \)
- \( \frac{5x^3}{4} - 2x^2 + \frac{3}{4}x^2 \)
- \( \frac{5x}{4} + \frac{3}{4}x^2 \)
- \( \frac{5x}{4} - 2 + \frac{3}{4}x^2 \)
None of the options provided directly match or are equivalent to the simplified form \(x^2(5x + 26)\) or \(5x^3 + 26x^2\).
It seems there might be a misunderstanding or a typo in the expression that was provided because none of the options accurately represent the simplification of \(5x^3 - 8x^2 + 34x^2\).
