# Math Help - Equation

1. ## Equation

$9x^2-12x+1=0$

And since I couldn't go any further with it I thought it might be no solution

$(3x -?)(3x -?)$

you're doing complex numbers now right? which means your quadratics will always have solutions, just perhaps, not real ones.

if factoring is a problem, use the quadratic formula

3. $9x^2-12x+1=(3x-2)^2-3.$

4. To be honest, I'm still confused. We're on the radical chapters, I don't know why I got asked that question. But I'll try the quadratic forumla for it.

5. Sure.

Then you want an expression like this

$(3x - 2)^2 - 3 = (3x - 2)^2 - \left( {\sqrt 3 } \right)^2 = \left( {3x - 2 + \sqrt 3 } \right)\left( {3x - 2 - \sqrt 3 } \right).$

Now you have radicals there.
