Answer:
x=-4.5 or x=-2/9(fraction)
Step-by-step explanation:
3x^2-6x-2=0 simplify so add 3 minus 6 then do ^2
-9x-2=0 Add 2 on both sides
-9x=2 divide by -9 on both sides
x=-4.5 or x=-2/9
Answer:
[tex]$x=\frac{3\pm\sqrt{15}}{3}$[/tex]
Step-by-step explanation:
[tex]3x^2-6x-2=0[/tex]
Using the quadratic formula to solve:
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
[tex]$x=\frac{-(-6)\pm\sqrt{(-6)^2-4(3)(-2)}}{2(3)}$[/tex]
[tex]$x=\frac{6\pm\sqrt{36+24}}{6}$[/tex]
[tex]$x=\frac{6\pm\sqrt{60}}{6}$[/tex]
[tex]$x=\frac{6\pm2\sqrt{15}}{6}$[/tex]
[tex]$x=\frac{3\pm\sqrt{15}}{3}$[/tex]
[tex]$x\approx{-0.291}, x\approx{2.291}$[/tex]
