Question

Hello, I need some assistance solving these 3 problems, I have about 20 to do similar to these 3.

Answer 1

#3
\[[x/(x-1)+1]/[(x+2)/x]\]\[[x+(x-1)/(x-1)]/[(x+2)/x]\]\[[(2x-1)/(x-1)]/[(x+2)/x]\]\[[x(2x-1)]/[(x-1)(x+2)]\]

Answer 2

#2
\[(x^2+6x+8)/(x^2-4)\]
\[[(x+4)(x+2)]/[(x+2)(x-2)]\]
\[(x+4)/(x-2)\]

Answer 3

#1
\[1/(ab)-2/(b^2)\]
\[b/(ab^2)-2a/(ab^2)\]
\[(b-2a)/(ab^2)\]
