Answer:

The exact values of roots:


$x_(1)=(-3+√(33))/(6)$


$x_(2)=(-3-√(33))/(6)$

Approximation:


x_(1)\approx0.457


x_(2)\approx -1.457

Explanation:


3x^2 + 3x =2\\3x^2 + 3x -2=0

Using the quadratic formula:


$x=(-b\pm √(b^2-4ac))/(2a)$


$x=(-3\pm √(3^2-4\cdot \:3\left(-2\right)))/(2\cdot \:3)$


$x=(-3\pm√(33))/(2\cdot \:3)$


$x=\frac{-3\pm√(33)}6}$
