Answer:
Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials.
Step-by-step explanation:
How do I combine like terms?
1. Step 2: Combine the coefficients.
2. 5h + 11g + 1h - 8g.
3. (5 + 1)h + (11 - 8)g.
4. 6h + 3g.
5. Step 1: Organize your like terms.
6. 5x + 8x + 10x2 - 7x2 - 4x.
7. Step 2: Combine the coefficients. (5 + 8 - 4)x + (10 - 7)x2 9x + 3x2
