Answer 1

Heres what I got :)

Answer 2

Answer:
`\bold{(-2\pm √(22))/(3)}`

Explanation:

`3x^2+4x-6=0\quad \rightarrow \quad a=3,\ b=4,\ c=-6\\\\\\\text{Quadratic formula is: }x=(-b\pm √(b^2-4ac))/(2a)\\\\\\x=(-(4)\pm √((4)^2-4(3)(-6)))/(2(3))\\\\\\.\ =(-4\pm √(16+72))/(2(3))\\\\\\\\.\ =(-4\pm √(88))/(2(3))\\\\\\\\.\ =(-4\pm 2√(22))/(2(3))\\\\\\\\.\ =(-2\pm √(22))/(3)`
