Homework Help: Math

Posted by Christine on Friday, August 7, 2009 at 10:52am.

Can someone please check my answers below for accurateness? The instructions are: Differentiate and simplify.

1) y=(2x^2+3x-1)(3x^2-5x-3)

2) y=(5x^2+3x-1)(3x^2-5x-3)


4) y=[5x^4-3x^3+6x^2-5x+7-x^(3/2)]/x^2

5) y=(5x^2-3x+7)(3x^2+7x-2)(6x^2+4x-5)

6) y=(7x^3-5x^2+6x-3)^12

7) y=(4x^2+3)^5(2x^2-1)^4

8) y=(4x^2+3x-5)^(4/5)

O.K. Bold the wrong answers or let me know which ones I should double check and fix. Thanks for your help and I really appreciate it because there are no answers to these questions in the back of the book, so I need to know if they are correct. Thank you once again!
