Simplifique cada una de las siguientes expresiones

   6) (x^4y^2z^7)/(2x^3y^4z^7)

var('x,y,z')
(x, y, z)
pol1 = x^4*y^2*z^7
pol2 = 2*x^3*y^4*z^7
simplify (pol1/pol2)
1/2*x/y^2

   8) [x3y(3x^4+5)^3]/[x^4y^9(3x^4+5)^7]

var('x,y')
(x, y)
pol1 = x*3*y*(3*x^4 + 5)^3
pol2 = x^4*y^9*(3*x^4 + 5)^7
simplify (pol1/pol2)
3/((3*x^4 + 5)^4*x^3*y^8)

   14) [x^2-3/x^2-8x+12]+[2x-1/x^2-8x+12]-[x+2/x2-8x+12]

var('x')
x
pol1 = (x^2 - 3)/(x^2 - 8*x + 12)
pol2 = (2*x - 1)/(x^2 - 8*x + 12)
pol3 = (x + 2)/(x^2 - 8*x + 12)
factor (pol1+pol2-pol3)
(x + 3)/(x - 6)

   15) [(3x-2)/(2x^2-5x-3)]-[(x-2)/(6x^2+x-1)]-[(2x+2)/(3x^2-10x+3)]

var('x')
x
pol1 = (3*x - 2)/(2*x^2 - 5*x - 3)
pol2 = (x - 2)/(6*x^2 + x - 1)
pol3 = (2*x + 2)/(3*x^2 - 10*x + 3)
factor (pol1-pol2-pol3)
2/(3*x - 1)
