Divide (x^3 - 8) ÷ (x - 2) x³ − 8x − 2 = x² + 2x + 4
Synthetic (x^3 - 2x^2 - 5x + 6) ÷ (x - 3) x³ − 2x² − 5x + 6x − 3 = x² + x − 2
Divide (6x^2 + 5x - 4) ÷ (2x - 1) 6x² + 5x − 42x − 1 = 3x + 4
Divide (x^2 - x - 12) ÷ (x - 4) x² − x − 12x − 4 = x + 3
Divide (x^2 + 7x + 10) ÷ (x + 5) x² + 7x + 10x + 5 = x + 2
Divide (2x^2 + 3x - 5) / (x - 1) 2x² + 3x − 5x − 1 = 2x + 5
Synthetic (x^2 + 2x - 8) ÷ (x - 2) x² + 2x − 8x − 2 = x + 4
Synthetic (x^2 - 9x + 20) ÷ (x - 5) x² − 9x + 20x − 5 = x − 4
Divide (x^3 - 2x^2 - 5x + 6) ÷ (x - 3) x³ − 2x² − 5x + 6x − 3 = x² + x − 2
Divide (x^2 + 4x + 7) ÷ (x + 1) x² + 4x + 7x + 1 = x + 3 + 4x + 1
Divide (3x^2 - 10x + 3) ÷ (x - 3) 3x² − 10x + 3x − 3 = 3x − 1
