Solve 14/(x^2-3x) - 8/x > -10/(x-3)

OpenStudy (anonymous):

Well you want to first open the brackets and get x on one side by itself

OpenStudy (anonymous):

You have to also consider the separate cases of when x is positive and when its negative

OpenStudy (watchmath):

rewrite the inequality as 14/(x^2-3x) - 8(x-3)/(x^2-3x) > -10x/(x^2-3x) or (14-8(x-3)+10x)/(x^2-3x) > 0

sorry i was away from my computer for a minute.

OpenStudy (anonymous):

so then I have 38+2x/x^2-3x>0

OpenStudy (anonymous):

@watchmath what do i do with this next

OpenStudy (watchmath):

ok so you have (38+2x)/(x(x-3)) >0. Draw a number line and put the point x=-19, x=0, x=3 on it. Then check the sign of (38+2x),x, (x-3) on each subinterval and find out which subinterval that gives (38+2x)/(x(x-3)) is positive

Here are your answers. x>3, that's your solution. Integer solutions are. x=-18 x=-17 x=-16

thank you both!
