3x2 + 9x + 2 is an expression; it is NOT an equation. You cannot solve an expression.
However, if you did have an equation: 3x2 + 9x + 2 = 0
Then dividing through by 3 gives: x2 + 3x + 2/3 = 0
or x2 + 3x = - 2/3
Completing the square on the left (add 9/4 to both sides) : x2 + 3x + 9/4 = 9/4 - 2/3 = 19/12
(x + 3/2)2 = 19/12
(x + 3/2) = +/- sqrt(19/12)
So x = -3/2 +/- sqrt(19/12)
