Best ResponseYou've already chosen the best response.0first solve it as if it were an equation \[ \large x^23x+2=0 \]

Best ResponseYou've already chosen the best response.1it's a parabola. To find where it crosses xaxis, write it like this: x^23x+2=(x1)(x2)=y so it will cross xaxis at x=1 and x=2 since you lookiing for points that are less than 0 it will be the part that is between this two points: dw:1351781925843:dw

Best ResponseYou've already chosen the best response.0the inequality has only ONE variable. its graph CANNOT bidimensional.

Best ResponseYou've already chosen the best response.0anyways. myko just gave the answer \[ \large 0=x^23x+2=(x1)(x2) \] so x=1 or x=2

Best ResponseYou've already chosen the best response.1look my last drawing x^23x+2=y is a function with range (vertex, infinity) it is less or equal 0 in the part that is under xaxis. That's what i drowed

Best ResponseYou've already chosen the best response.1i gave the cross points to be able to grapfh it. The answer is the part under x.axis

Best ResponseYou've already chosen the best response.1@aussy123 don't be confused by @helder_edwin . The graph you looking for is: dw:1351782419649:dw

Best ResponseYou've already chosen the best response.1Oh I see , @myko , I had to reread your first comment to get it, thanks because my book is giving me alot of confusing stuff

Best ResponseYou've already chosen the best response.0again. the problem says: graph \(x^23x+2\leq0\) it does NOR say graph \(x^23x+2\leq y\).

Best ResponseYou've already chosen the best response.1How do you GRAPH this x2 3x + 2<= 0

Best ResponseYou've already chosen the best response.0it is a onedimensional problem (one variable) but u turned it into a twodimensional problem by adding a "y" that was never there.

Best ResponseYou've already chosen the best response.1x2 3x + 2 represents values of y, dude.

Best ResponseYou've already chosen the best response.0but it was never there. u r not graphing a function "dude".
