To simplify the expression 7x + 34x² + 3x + 6, we start by identifying like terms.
The expression can be broken down as follows:
- Terms with x²: 34x² (this term stands alone)
- Terms with x: 7x and 3x
- Constant term: 6
Next, we combine the like terms:
- For the x terms:
- 7x + 3x = 10x
So, the expression now looks like:
34x² + 10x + 6
Therefore, the correct simplification of the expression 7x + 34x² + 3x + 6 is:
34x² + 10x + 6.
