Question 295914: (25-2x)(10-2x)(x)-175<=0
How do I find the roots of this problem? The three answers for x that I come up with are (0,5,12.5). All of these satisfy the equation, but my actual problem is one of volume and zero is not a good height in my opinion.

Question 300818: I'm at a lose here. I've derived an answer but I'm lost as to whether it is correct.
Find the LCD for the given rational expressions, and convert each rational expression into an equivalent rational expression with the LCD as the denominator.
(-3)/(2p^2+7p-15),p/(2p^2-11p+12),2/(p^2+p-20)
1.  ,  , 
2.  ,  , 
3.  , , 
4.  ,  , 
5.  ,  , 
I cam up with 5 as my equation had (2p-3)(p+5)(p-4) as the LCD. Any help with this would be much appreciated.
