Question

examen de 4 divisiones ; de polinomio por polinomios 1)x2-2-x3 /x+1 2) x2-11x+30 /x6 3)-15x2+22xy-8y2 /-3x+2y 4)14x2+22x-12/7x-3

Answer 1

1) x² - 2x - 3/x+1 = (x-3) (x+1) / (x+1) = x-3
2) x² - 11x + 30 / x-6 = (x-6)(x-5) / (x-6) = x-5
3)- 15x² + 22xy - 8y² / -3x+2y =(-3x+2y)(5x-4y) / (-3x+2) = 5x - 4y
4) 14x² + 22x - 12 / 7x -3 = (7x-3)(2x+4) / (7x-3) = 2x+4
