Please help with these 5 problems!
I have the solutions but I don't understand how to get them!
1. Perform the indicated operations and simplify:
[(2/x)1]/(x^2 4)
2. Subtract and simplify:
[12/(x^2 4)]  [(3x)/(x^2 + 2x)]
3. Perform the indicated operations and simplify:
[(x/y)(y/x)]^1
4. Divide and simplify:
[(a^2 b)/(ab)]/[(a+b)/(a^2b^2)]
5. Perform the indicated operations and simplify
[(x/x3)(2x/x^22X3)]/[(2/x+1)(1/x)
Solutions:
1. 1/(x^2 + 2x)
2. [x^2 + 7x + 6]/[x(x+z)(xz)]
typo in book?
3. xy/(x^2  y^2)
4. a^2 b
5. x^2/(x3)

1. Rewrite (2/x) 1 in the numerator as (x2)/x
Factor (x^2/4) in the denominator as (x2)(x+2)
Then cancel out the (x2) terms in numerator and denominator. You wil be left with 1/[x(x+2)]
3. Rewrite x/y and y/x with a common denominator, xy.
[(x^2 y^2)/xy]^1 = xy/(x^2 y^2)
You try the others. They are all exercises in factoring and canceling tems
