is it \[\frac{x^2}{3}x+\frac{5}{3}=0\]?

@satellite73 You got it right just change the +5/3 to 5/3

if so, start by multiplying everything by \(3\) to get \[x^23x5=0\]

\[1/3\,{x}^{2}x5/3\] that is what maple translates it to

unfortunately i don't think this one factors, as a matter of fact i am sure it does not

so you have to use the quadratic formula

so complete the square :) Also i think it is a good idea to say expression=0 when you say solve. Other wise we imply you mean = to 0

@timo86m Yeah this is my first time using open study so im trying to my best, lol bare with me. Okay can you show me step by step how to complete the square?

use \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\] with \(a=1,b=3,c=5\) i would not complete the square for this one

satallite already started in quadratic formula instead

satellite73Best ResponseYou've already chosen the best response.1
if you want to complete the square, which the quadratic formula does for you in one step, you have to start with \[x^23x=5\] then take half of 3, which is \(\frac{3}{2}\) and write \[(x\frac{3}{2})^2=5+\frac{9}{4}=\frac{27}{4}\] and so \[x\frac{3}{2}=\pm\frac{\sqrt{27}}{2}\] making \[x=\frac{3\pm\sqrt{27}}{2}\]

altho i am pretty sure you will have to learn completing the square sooner or later :)

except i made a mistake, \(5+\frac{9}{4}=\frac{29}{4}\)

Ok, thank you guys! :) @timo86m @satellite73

in any case if the middle term is odd,(3\) is odd, then it is easier to use the quadratic formula
