Solve the inequality $x^3  + 4x > 5x^2$.

x ( x^2 - 5x+4) > 0

x(x-4)(x-1) >0                        (0,1) U (1,+inf)     (by graphing ....easiest)

factor to get x(x-1)(x-4)=0 so the answer is: 

 

 (0, 1) U (4, infinity)

 

using this as a system of inequalities for a solution won't work because for some reason web2.0calc can't render it

 

just convert (0, 1) U (4, infinity) into a system of inequalities for a solution if that's what you're looking for
