Ok I understand everything about surds (yes everything!) But this is 1 thing I dont get.
I know how to solve an inequality involving a surd but what I get dont is why and how the inequality sign changes?
in this textbook it goes from
root3 +5/ 4root3+2 > x
but then underneath it says
x< root3 +5/ 4root3+2 * root3 +5/ 4root3-2
what I dont get is why has the inequality sign just reverseD?
