Best ResponseYou've already chosen the best response.0x^2 = 6,4 for the LHS if I did it right in me head. x = 0,2,2 for the RHS..... I wonder if that helps....

Best ResponseYou've already chosen the best response.0x^4 +x^3 10x^2 +4x +24 < 0

Best ResponseYou've already chosen the best response.0that should be ...x^3.... typo :)

Best ResponseYou've already chosen the best response.0So, what goes inside the brackets

Best ResponseYou've already chosen the best response.0dunno yet, still trying to factor it, I got so far: (x2)(x+2)(x+2)(x3) We put these on a number line to see which of these makes everything less than 0....

Best ResponseYou've already chosen the best response.0if I did it right: (inf,2) or (2,3)

Best ResponseYou've already chosen the best response.0the easiest way to determie the values are to draw a number line and put in the values that make the equation equal to zero. Take each value and to the left of it, put a () and to the right of it put a (+); then multiply your signs together to get area that are (+) and (). then pick the areas that fit the equation :)

Best ResponseYou've already chosen the best response.0Actually, once you have it factorised, it is probably easier to quickly sketch the graph of the quartic function.

Best ResponseYou've already chosen the best response.0X^410x^2+24< x^34x subtract the RHS from the LHS. x^4 x^3 10x^2 +4x +24 >0 right?

Best ResponseYou've already chosen the best response.0<0 .... typo again... its these fat fingers and this tiny little keyboard :)

Best ResponseYou've already chosen the best response.0the LHS factors to: (x2)(x+2)(x3)(x+2) right? remultiply to check thatits right...

Best ResponseYou've already chosen the best response.0M Dot cancelled a factor of (x+2) at some point... best not to ever do that with a factor unless you can be sure it is >0 ∀ x ∈ R or it flips the inequality.

Best ResponseYou've already chosen the best response.0<.......2.........2.........3.......>  + + +   + +    +   +  + if I did it right, these are my results for the number line....

Best ResponseYou've already chosen the best response.0but something seems off, the even degree should be positive at both ends...

Best ResponseYou've already chosen the best response.0The answer is only 2< x <3 , not x<2

Best ResponseYou've already chosen the best response.0ahhh..... that seemes more plausible :)

Best ResponseYou've already chosen the best response.0x^410x^2+24\le x^34x. The instructor wants x\[\epsilon\] and U

Best ResponseYou've already chosen the best response.0U is the universal set right?

Best ResponseYou've already chosen the best response.0can you do calculus on it? :)

Best ResponseYou've already chosen the best response.0This is an algebra class. I'm familiar with any calculus

amistre64

Best ResponseYou've already chosen the best response.0bummer.... calculus would allow us to "see" what is happening at cetain points on the graph more easily

amistre64

Best ResponseYou've already chosen the best response.0it appears that the graph touches then turns at x = 2 .... which is why it is positive on both sides of it....

Best ResponseYou've already chosen the best response.0so it "crosses" the x axis at 2 and 3 which make it go negative AND less than 0

amistre64

Best ResponseYou've already chosen the best response.0so your notation would be [xx is an element of (2,3)} or some such notation

Best ResponseYou've already chosen the best response.0I am unclear about the "U" set, its been qwhile since I had to play in set theory :)
