Question 1207666: Find the real solutions by factoring.


x^2 + sqrt{3}x^2 - 3 = 0


Let x^4 = (x^2)^2

Let u = x^2

u^2 + sqrt{3}x - 3 = 0

Stuck here....

Can I use the quadratic formula?

.

Your starting equation is THIS

     +  - 3 = 0.


It is the same as

     +  = 3.


Factor left side

     = 3.


Divide both sides by    and express x^2 explicitly

    x^2 = .


Get rid of irrationality in the denominator

    x^2 =  =  =  = .


Now take square root of both sides and find x

    x =  = 1.047891...


ANSWER.  x =  = 1.047891  (rounded).

Solved.
