1+ 1/x = 6/x2
x2(1+ 1/x) = 6
x2 + x = 6
x2 + x -6 = 0
(x+3)(x-2)=0

I believe the answer is x= -3 or x = 2

-18x2y3z/-3xyz = Divide numerator and denominator by -3
6x2y3z/xyz= Divide numerator and denominator by xyz
6 (2*3)=   Multiply
6*6=36

m3 - m=
m(m2-1)=  Factor out m
m(M-1)(m+1)
m= =1 or -1

x-5 / x - x / x-5
not sure about this one

5x + 5 / x+3 * 2x+6 / x2+2x+1   Factor and cancel
5(x+1)/x+3 * 2(x+3)/(x+1)(x+1)
5/1 * 2/x+1
10/x+1  
not sure what the next step is
