Best ResponseYou've already chosen the best response.14x^5  18x^4 + 18x^3 ≥ 0 divide it by x^2 so it's 4x^3  18x^2 + 18x ≥ 0 for the x>0 it's 4x^2  18x + 18 ≥ 0 (first graph) and for the x <0 it's 4x^2  18x + 18 < 0 (second graph) if you draw the first graph the the impossible rations for x>0 is \[\left( 0 , 1.5 \right) \cup \left( 3 , \infty \right) \cup \ { 0 , 1.5 , 3}\] but the second graph for the x<0 doesn't have any rations so the total answer is \[\left( 0 , 1.5 \right) \cup \left( 3 , \infty \right) \cup \ { 0 , 1.5 , 3}\]

Best ResponseYou've already chosen the best response.0Now I understand, so when solving the inequality, 2 graphs will be drawn before the final graph?

Best ResponseYou've already chosen the best response.1the point is that you divide an inequality by variable that can be negative you should separate it to two inequality one for the negative variable and one for the positive variable

Best ResponseYou've already chosen the best response.1all of 'em i meant the sum of each seperated graph's answer

Best ResponseYou've already chosen the best response.1you separated the inequality into two inequality when you divide it by a variable i meant the answer is the sum of the separated inequality's answer
