Best ResponseYou've already chosen the best response.1is it \[\frac{x^2}{3}x+\frac{5}{3}=0\]?

Best ResponseYou've already chosen the best response.0@satellite73 You got it right just change the +5/3 to 5/3

Best ResponseYou've already chosen the best response.1if so, start by multiplying everything by \(3\) to get \[x^23x5=0\]

Best ResponseYou've already chosen the best response.1unfortunately i don't think this one factors, as a matter of fact i am sure it does not

Best ResponseYou've already chosen the best response.1so you have to use the quadratic formula

Best ResponseYou've already chosen the best response.0so 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

Best ResponseYou've already chosen the best response.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?

Best ResponseYou've already chosen the best response.1use \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\] with \(a=1,b=3,c=5\) i would not complete the square for this one

Best ResponseYou've already chosen the best response.0satallite already started in quadratic formula instead

Best ResponseYou've already chosen the best response.1if 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 \[x=\frac{3\pm\sqrt{27}}{2}\]

Best ResponseYou've already chosen the best response.0altho i am pretty sure you will have to learn completing the square sooner or later :)

Best ResponseYou've already chosen the best response.1except i made a mistake, \(5+\frac{9}{4}=\frac{29}{4}\)

Best ResponseYou've already chosen the best response.1in any case if the middle term is odd,(3\) is odd, then it is easier to use the quadratic formula
