Help me "simplify"
Ok my teacher has robbed me of points, seriously I'm tired of teachers stealing points from me because when your asked to simplify an expression your asking someone to do something that can't clearly be defined... you'll never ever come up with a clean cut definition of what it means to "simplify", people in like the sixth grade are taught to simplify by just combining terms together like
x - 4x = 3 -x
fine in the sixth grade if people can't "simplify" this to
-2x = 3
and solve for x
x = -3/2
sure take points off their grade but holy cow... in calculus a teacher is really going to take points off for not "simplifying completely" holy cow... we can't even define this term...
well you so I had to do a summer assignment and I handed it in and she stole points from me... I don't understand why... I know that there's something such as a ireducable simplification form or whatever you want to call it were you can't simplify furher... but please help me understand why this teacher is stealing points from me for no real reasonable reason at all here's the problems were I think taking points off from my grade is unreasonable...
Example 1: Simplify ((x+1)^3(x-2)+3(x-1))/((x+1)^4)
and I put for my answer
(x-2)/(x+1) + 3/(x^3 + 3x^2 + 3x + 1)
and she put a big orange x over it... so my question to you is why? What would be a more correct answer?
Example 2: Simplify (x^(1/2) - x^(1/3))/x^(1/6)
and I put for my answer
x^(1/3) - x^(1/6)
another big orange x... I have no clue why this is wrong... can someone please explain this to me... how can I write this more simple?
Thanks
