nice algebra problem

[@ranjankumarmalla8406]

25x^2=9x
Deviding both sides by x we have
25x=9
x =9/25 answer.

[@GetMeThere1]

That's what I saw, too. But it doesn't give you zero as an answer -- and it is one.

[@vasilizrl9125]

Bro you can't divide by x if you are not sure that x does not equal 0.... for the fact, x1=9/25 but x2=0. For that reason you definitely can't divide by 0

[@GetMeThere1]

@@vasilizrl9125 Well, it did produce a verifiable answer though.

Is this the junior Olympiad? Seems very easy for an Olympiad problem.

Please i have a question in image how can you help me solve please

[@collinsmensah9312]

Please how do I get the question to you

3√x = 5x (squaring both side)
9x = 25x²
25x² - 9x = 0
x(25x - 9) = 0
So, x = 0 or
25x - 9 = 0
Or x = 9/25

[@adgf1x]

x=9/16=0.5625

[@alexfisher2848]

25х^2=9х (divide both sides by x)
25х=9
х=25/9.

[@vasilizrl9125]

The problem with that solution is that you don't know if x=0 so you cannot just divide by it (btw there are 2 solutions x1=9/25 and x2=0).
