6e2+11e−1
6 e squared plus 11 e minus 1

6e2+e−5

Answer 1

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

Here are the steps:

1. Combine the \(e^2\) terms: \[ 4e^2 + 2e^2 = 6e^2 \]

2. Combine the \(e\) terms: \[ -5e + 6e = 1e \quad \text{or just } e \]

3. Combine the constant terms: \[ 2 - 3 = -1 \]

Putting it all together, we have: \[ 6e^2 + e - 1 \]

So, the correct simplified expression is: 6e² + e - 1 (the option 6 e squared plus e minus 1).
