2a+3a-2=5a-2
-4a-2b-2b-a=-5a-2b
-3x-6ykeadratu-y-xkwadratu=-2x-7y
2(a+3)(3a-2) = 2(3a² - 2a + 9a - 6) = 6a² - 4a +18a - 12 = 6a² + 14a - 12
(3a² - b)(a² - 2b) = 3a⁴ - 6a²b - a²b + 2b² = 3a⁴ -7a²b + 2b²
-4 (a - 2b) (2b - a) = -4 (2ab - a² - 4b² + 2ab) = 4a² +16b² - 16ab
(2x² - 3y²) (2x² + 3y²) = 4x⁴ - 9y⁴
(-x³ + 4y³) (3x³ - 2y) = -3x⁶ + 2x³y + 12x³y³ - 8y⁴
-3 (x - 2y²) (y - x²) = -3 (xy - x³ -2y³ + 2x²y²) = -3xy + 3x³ + 6y³ -6 x²y²
