I’m not sure about how to combine like terms i need

okay so it really easy. EX: 6x + 4x^2 - 2x + 3x^2 - 7x^5

So basically 6x - 2x because both of them have x and are raised to the power of 1. While  4x^2 + 3x^2 go together because they are both raised to the 2nd power. While -7x^5 doesn't go with any terms because no terms are raised to the 5th power.

Step 2: Combine the coefficients.

5h + 11g + 1h - 8g.

(5 + 1)h + (11 - 8)g.

6h + 3g.

Step 1: Organize your like terms.

5x + 8x + 10x2 - 7x2 - 4x.

here is an example
