HARMEET SINGH. 1) el factor es ax es la respuesta b) 2) obtendremos tres factores ya que su máximo exponente es 3 Respuesta C) 3) En la ecuación la solución es la opcion a) 12 ya que 12/3 + 12/2 = 10 4 + 6 = 10 10 = 10 espero que te sirva, salu2!!! (a+b)2 = a2+2ab+b2 (a-b)2 = a2 - 2ab+b2 (a+b) (a-b)2 = a2 - b2. Therefore: a^2 - b^2 = ab - b^2 Therefore: (a + b)(a - b) = b(a - b) Now divide both sides by (a - b) Therefore: a + b = b But since a = b and substituting b for a Therefore: b + b = b Therefore: 2b = b Now divide both sides by b Therefore: 2 = 1 QED This doesn't work because in line 5 both sides of the equation are divided by (a-b).
