To simplify the expression 6x² + 3 + 5x³ + 4x³ + 2x² + 8, we first combine like terms.
1. Start by grouping the like terms together:
- For the x³ terms: 5x³ + 4x³ = 9x³
- For the x² terms: 6x² + 2x² = 8x²
- For the constant terms: 3 + 8 = 11
2. Now we can rewrite the expression by combining all these results:
9x³ + 8x² + 11
This is the simplified form of the original expression.
