what is the smallest sloution to the equation x to the fourth - 34x to the 2 +225=0

So, you can factor this into a pair of quadratics. Basically, you have this: $x^4 - 34x^2 + 225 = 0$ Imagine that $$u = x^2$$. Then you have: $u^2 - 34u + 225 = 0$ So first you solve for $$u$$. Then, you have $$u = x^2$$, so $$x = \sqrt{u}$$. Does that help?
