Question

Some e Subtraia os monômios:
1. 4xy + 2xy² + 5xy – 5x³y + 2xy²
2. 2x + 4y - 3xy - 5y – 6x
3. 8xy + 3x²y – 6xy² + 3xy – 2x²y + 8xy²
4. 2x² + 6y³ - 2xy – 4x² + 2y³ + 4xy
5. 9y² + 4x³ - 5xy – 4y² - 1x³ + 6xy

Answer 1

1. 2x + 4y - 3xy - 5y – 6x

2. 8xy + 3x²y – 6xy² + 3xy – 2x²y + 8xy²

3. 2x² + 6y³ - 2xy – 4x² + 2y³ + 4xy

4. 9y² + 4x³ - 5x

1. 2x + 4y - 3xy - 5y – 6x

(2x - 6x) + (4y - 5y) - 3xy

-4x + (-5y) - 3xy

-4x - 5y - 3xy

2. 8xy + 3x²y – 6xy² + 3xy – 2x²y + 8xy²

(8xy + 3xy) + (3x²y - 2x²y) + ( 8xy² - 6xy²)

5xy + 1

x²y + 2xy²

3. 2x² + 6y³ - 2xy – 4x² + 2y³ + 4xy

(2x² - 4x²) + (6y³ + 2y³) + (4xy - 2xy)

-

2x² + 8y³ + 2xy

4. 9y² + 4x³ - 5xy – 4y² - 1x³ + 6xy

(9y² - 4y²) + (4x³ - 1x³) + (6xy - 5xy)

5y² + 3x³ + 1xy
