Question

Solve for x.

3x^2-6x-2=0

Answer 1

x=-4.5 or x=-2/9(fraction)

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 2

`$x=(3\pm√(15))/(3)$`

Explanation:

`3x^2-6x-2=0`

Using the quadratic formula to solve:

`$x=(-b\pm√(b^2-4ac))/(2a)$`

`$x=(-(-6)\pm√((-6)^2-4(3)(-2)))/(2(3))$`

`$x=(6\pm√(36+24))/(6)$`

`$x=(6\pm√(60))/(6)$`

`$x=(6\pm2√(15))/(6)$`

`$x=(3\pm√(15))/(3)$`

`$x\approx{-0.291}, x\approx{2.291}$`
