Algebra

[Asimov Pupil]

This is my first assignment of my first math class or my first year of univercity and they said i should have learned this in grade 11, (too long ago to recall really) so i want to make sure i got them right (which i doubt!) here's how it is, i will give the question and my answer and if i am wrong please tell me.

 

1) [math]\frac{5x^4}{\sqrt{x^3-6}}+x\sqrt{x^3-6}[/math]

 

solution: [math]\frac{6x^4-6x}{\sqrt{x^3-6}}[/math]

 

2) [math]\frac{\frac{x^2-x-6}{4x-12}}{\frac{2x+6}{x^2+5x+6}}[/math]

 

solution: [math]\frac{(x+2)^2}{8}[/math]

your answer appears to be correct.

 

||edit well the first one is

...except that you haven't stated what the question asks for. You have merely provided an expression and asked for an answer.

 

Yes, it's obvious that you are required to simplify the provided expression, but unless you state this explicitly, the question does not exist.

 

Henceforth, please state the question in its entirety.

the 1st one is correct... and i believe the 2nd is also correct.

I came up with what you did. Not sure if they can be simplified any more though.

sry for not specifying, it says just simplify,

 

the first one can have more operations done to it but it cannot cancel anything else so there is no point.

 

thank you
