Answer 2

Zasa,
Vamos paso a paso

a)
           factor comun = (x - y)
                 = (x - y)(9 - 4x^2)
                                                  9 - 4x^2 = diferencia de cuadrados
                                                  (3 - 2x)(3 + 2x)
                 = (x - y)(3 - 2x)(3 + 2x)
b)
           factor comun = (2x + y)
                = (2x + y)(x^2 + 2x + 1)
                                                      x^2 + 2x + 1 = cuadrado perfecto
                = (2x + y)(x + 1)^2
             o
                = (2x + y)(x + 1)(x + 1)
c)
      igual b)
                = (x - 2y)(x^2 - 2x + 1)
                = (x - 2y)(x - 1)^2
             o
                = (x - 2y)(x - 1)(x - 1)
