If x^2-36>0,what are the possible values of x ?
x^2>36 \[x \ge \pm6\]
Options provided, A) x > 6 B) x < 6 C) x > -6 D) x <-6 or x >6
@Rosh007 Yes ?
@Rosh007 Please help !
So x > +- 6
D
mmmm... I am not sure about how it comes.. since it is inequality... have to refresh.. my memory...
@nubeer Please help !
if you want to solve, try factor the x^2 - 36 ...and what condition make the product of 2 factors greater than zero ?...try that, you should come out with the right answer
not helpful ^^
solving for you is not the right way to help you understand at all :)
but a method is there.... not by mathematical.. but by anaysis... you will b able to understand
hmm honestly.. i dont remmeber how but option is D. u can say its trick the way i rmemeber when x<+-a then sol is -a<x<a when x>+-a then sol is x<-a and x>a
@tamtoan I dont need the answer,i dont even care about the answer
it is best suited for inequality
what will i do of the answer lol :D
@Rosh007 Well it is fun to revise things back after 2 years,Rusted brains lol.
did you try factoring x^2 - 36 ? what are the 2 factors ?
