a)
x - y
3x - 3y = 3(x - y)
x² - y² = (x + y)(x - y)
El mcm es el producto de los factores primos comunes y no comunes:
mcm = 3(x - y)(x+y) = 3x² - 3y²
b)
x² + 3x + 2 = (x + 2)(x + 1)
x² + 4x - 5 = (x + 5)(x - 1)
mcm = (x + 2)(x + 1)(x + 5)(x - 1)
c)
x² + x - 2 = (x+2)(x-1)
x² + 3x + 2 = (x+2)(x+1)
x² - 1 = (x+1)(x-1)
mcm = (x+2)(x+1)(x-1) = x³ + 2x² - x - 2
