Question 734411
Fist step is to make all fractions have the same denominator,

   (3x+(3x-10)*x^2) / X^2 - (2x+(x-6)*x^2) / x^2)

we can now combine numerators over the denominator x^2

     (3x+(3x-10)*x^2 - 2x + (x-6)*X^2) / x^2

multiply the x^2 term in the numerator

(3x+3x^3-10x^2-2x-2x^3+6x^2) / x^2

combine like terms in numerator

    (x^3-4x^2+x) / x^2

reduce by x

(x^2-4x+1) / x is the solution
