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
