Let's simplify the expression step by step. The expression you've provided is:
\[ 4 + 3x^2 - 2 - 23x^2 + 1 + 3x \]
First, we'll combine like terms:
- Constant terms: \(4 - 2 + 1 = 3\)
- \(x^2\) terms: \(3x^2 - 23x^2 = -20x^2\)
- \(x\) terms: \(3x\)
Now, let's combine everything together:
\[ 3 - 20x^2 + 3x \]
To write it in the standard form (usually written with the highest degree first):
\[ -20x^2 + 3x + 3 \]
So, the simplified expression with the fewest terms is:
\[ -20x^2 + 3x + 3 \]
