Answer 1

(9x - 6) - (4x² - 3x + 12) = - 4x² + 12x - 18

9x - 6 - 4x² + 3x - 12

12x - 18 - 4x²

- 4x² + 12x - 18

___________________________

3(6x² + 2x - 3) + 2(2x² - 3x + 2) = 22x² - 5

18x² + 6x - 9 + 2 (2x² - 3x + 2)

18x² + 6x - 9 + 4x² - 6x + 4

18x² - 9 + 4x² + 4

22x² - 9 + 4

22x² - 5

___________________________

1/2(8x² + 4x - 2) - 1/3(6x² + 3x - 9) = 2x² + x + 2

1/2 × 2 (4x² + 2x - 1) - 1/3 × 3(2x² + x - 3)

(4x² + 2x - 1) - (2x² + x - 3)

4x⁴ + 2x - 1 - 2x² - x + 3

2x² + x + 2

___________________________

(x² + 3x)² = x⁴ + 6x³ + 9x²

(x²)² + 2x² × 3x + (3x)²

x⁴ + 6x³ + 9x²

___________________________

(2x³ + 4x²)(x³ - 2x² + 3x) = 2x⁶ - 2x⁴ + 12x³

2x³ × (x³ - 2x² + 3x) + 4x² × (x³ - 2x² + 3x)

2x⁶ - 4x⁵ + 6x⁴ + 4x⁵ - 8x⁴ + 12x³

2x⁶ - 2x⁴ + 12x³
