But there should only be one answer...the positive one. So, what is it?
saifoo.khan

no, there will b 2 answers.

  • anonymous
I got 25/9
saifoo.khan
  • saifoo.khan
no, its 9/5 & 0.
anonymous
  • anonymous
Yeah. Your right Saifoo but then the positive one should be it....there should be a negative anser and a positive one.

Is it 5^2 or 5x^2 in the origianl problem?
anonymous
  • anonymous
okay...lol. here's whats up.
saifoo.khan
  • saifoo.khan
it is 5x^2

i think u typed the wrong ques

  • anonymous
i have a project due tommorrow for math I and i need someone to help tutor me on positive solutions of equations....can any of you two help me? please???
saifoo.khan
  • saifoo.khan
i think u typed the wrong ques
anonymous
  • anonymous
well i dont even think that was a possible equation that even existed...lol. i think ur right
anonymous
  • anonymous
saifoo is right if it is 5x^2 the answer would be 9/5 and 0
saifoo.khan
  • saifoo.khan
hmm. :)
anonymous
  • anonymous
hmmmm *twicee. :-))
anonymous
  • anonymous
interesting. well can any of you two give me an equation and explain to me how you get the positive solution of it?
anonymous
  • anonymous
factor out an x x(5x-9)=0
anonymous
  • anonymous
Yeah!!!! A problem like that is what I have on my paper. Now...how do I get the positive solution of this?
anonymous
  • anonymous
then set x=0 and 5x-9=0
anonymous
  • anonymous
Yeah. Then what?
anonymous
  • anonymous
will we know that x=0 is one answer. then let's solve 5x-9=0. once we solve that we get 5x=9 then divide 5 by both sides we get 9/5
anonymous
  • anonymous
dose that make sence?
anonymous
  • anonymous
hold on...
anonymous
  • anonymous
can we do another problem if you don't mind?
anonymous
  • anonymous
sure
anonymous
  • anonymous
i did this one but i want to make sure it's right: 4x^2 - 36 = 0
anonymous
  • anonymous
i got: the positive solution is 3.
anonymous
  • anonymous
am i right?
anonymous
  • anonymous
that is what I got... for 4x^2-36=0
anonymous
  • anonymous
so im right?
anonymous
  • anonymous
sorry that is what I got
anonymous
  • anonymous
No, it's 9/5. You factor out an x, and you use the zero product rule, setting x = 0 and (5x-9)=0, since, algebraically, you can do that. So, solving for x, you get x = 0 and x = 9/5
anonymous
  • anonymous
LOL. but i was talking about a different equation.....4x squared - 36 = 0
anonymous
  • anonymous
mknight94 we arewwe are doing a different problem
anonymous
  • anonymous
*not the 1st one
anonymous
  • anonymous
smartchickk59 you are right. are you sure that it is not 4x^2-36x=0?
anonymous
  • anonymous
not with the x after the 36
anonymous
  • anonymous
no its: 4x^2-36=0
anonymous
  • anonymous
3 is the answer
anonymous
  • anonymous
Did you need any more help?
anonymous
  • anonymous
Oh no thank you...not for now. But thank you so muchh for your help and your patince....!!! :) Thanks.
