Answer 1

1) 2x²-3x+6-5x²+x-9=-3x²-2x-3
2) 3u³-2uv²-v-5u³+3uv²+3v=-2u³+uv²+2v
3)4a³+8-3a²+a²-13-2a³=2a³-2a²-5
4)7x²-y²-5xy-3x²-2xy+4y²=4x²+3y²-7xy

Answer 2

Simplifying Expressions

To simplify the given expressions, we can combine like terms. Like terms are terms that have the same variables raised to the same powers. Let's simplify each expression step by step:

1) 2x² - 3x + 6 - 5x² + x - 9 - Combine the like terms with the same variable and exponent: - (2x² - 5x²) + (-3x + x) + (6 - 9) - -3x² - 2x - 3

2) 3u³ - 2uv² - v - 5u³ + 3uv² + 3v - Combine the like terms with the same variable and exponent: - (3u³ - 5u³) + (-2uv² + 3uv²) + (v + 3v) - -2u³ + u²v² + 4v

3) 4a³ + 8 - 3a² + a² - 13 - 2a³ - Combine the like terms with the same variable and exponent: - (4a³ - 2a³) + (-3a² + a²) + (8 - 13) - 2a³ - 2a² - 5

4) 7x² - y² - 5xy - 3x² - 2xy + 4y² - Combine the like terms with the same variable and exponent: - (7x² - 3x²) + (-5xy - 2xy) + (-y² + 4y²) - 4x² - 7xy + 3y²

These are the simplified forms of the given expressions. Let me know if you have any further questions!
