It seems like you are presenting a series of algebraic expressions or equations that need to be simplified or solved. However, the formatting is a bit unclear. I will do my best to interpret and provide assistance based on what you've provided.
Let's break down the elements:
The first part appears to be an equation involving \(x\): \[ x^2 + 3x + x - 3x = 2x \] Simplifying the left side: \[ x^2 + (3x + x - 3x) = 2x \implies x^2 + x = 2x \implies x^2 + x - 2x = 0 \implies x^2 - x = 0 \] Factor out \(x\): \[ x(x - 1) = 0 \] Thus, \(x = 0\) or \(x = 1\).
The second part is not entirely clear. If you're providing fractions or additional equations, please clarify what you want to solve or simplify. Here are some interpretations:
a) \[ 3 - x \]
b) \[ \frac{2^2 - 1}{5 - x} = 2x \]
If you need help with something specific like solving equations, finding limits, derivatives, etc., please clarify those points further.
If any of these interpretations are incorrect or if you have more specific questions, please provide additional information, and I'd be happy to assist you!
