Question 702409
<font face="Times New Roman" size="+2">


There is one right next to the lead coefficient 4 and another right next to the -9 coefficient on the 1st degree term.


Oh!  You meant, "how do I find the <i><b>value</b></i> of *[tex \LARGE x]," didn't you?  You really should take the time to say what you mean so that we don't have to guess.


Let *[tex \LARGE u\ =\ x^{\small\frac{1}{4}}\LARGE].  Then *[tex \LARGE u^2\ =\ x^{\small\frac{1}{2}}\LARGE]. 



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 4u^2\ -\ 9u\ +\ 4\ =\ 0]


Use the quadratic formula


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ u\ =\ \frac{9\ \pm\ \sqrt{17}}{8}]. 


Then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ u^4\ =\ \left(\frac{9\ \pm\ \sqrt{17}}{8}\right)^4].


You can go ahead and do all of the ugly arithmetic.
