3x-1+x-9 x2

It seems like you have an expression that you want to simplify. Let's break down the expression you provided:

Given:

\[ 3x - 1 + x - 9 \]

First, we can combine like terms (the x terms and the constant terms):

1. Combine the \(x\) terms: \(3x + x = 4x\)
2. Combine the constant terms: \(-1 - 9 = -10\)

Putting it all together, we get:

\[ 4x - 10 \]

If you mean to include a division by \(x^2\), then we would write the whole expression as:

\[ \frac{4x - 10}{x^2} \]

This is the simplified form of the expression you've provided. If you have a different interpretation or additional terms, please clarify, and I can assist you further!
