To simplify the expression (6x^{2}+2x)+(5x-3x^{2}+4), we need to combine like terms.
First, let's rewrite the expression by removing the parentheses:
6x^{2} + 2x + 5x - 3x^{2} + 4
Next, combine the like terms:
- Combine the x^2 terms: 6x^{2} - 3x^{2} = 3x^{2}
- Combine the x terms: 2x + 5x = 7x
- The constant term remains: +4
So, the simplified expression is:
3x^{2} + 7x + 4
Therefore, the correct answer is:
3x^{2} + 7x + 4
