I dont know if you wanted the steps but:

x^2-4x-6=0

plug it into the equation:

$\frac{-(-4)\sqrt{(-4)^2-4(1)(-6)}}{2(1)}$

$[tex] \frac{4\sqrt{40}}{2}$ [/tex]

$\frac{4+2\sqrt{10}}{2} \frac{4-2\sqrt{10}}{2}$

$x=2+\sqrt{10}$

$x=2-\sqrt{10}$

x^2-4/3x+1/3 x=1 , x= 1/3

2x^2-3x+1=0 x=1 , x=1/2

6x^2+12x=-5

add the 5 to both sides

6x²+12x+5=0 plug the problem into the equation

x= $\frac{-12\sqrt{12^{2}-4(6)(5)}}{2(6)}$

x=[ $\frac{-12\sqrt{144-120}}{12}$

x= $\frac{-12\sqrt{24}}{12}$

x= $\frac{-12+2\sqrt{6}}{12}$ x= $\frac{-12-2\sqrt{6}}{12}$

$\frac{-6+2\sqrt{6}}{6} \frac{-6-2\sqrt{6}}{6}$
