If it's not what You are looking for type in the equation solver your own equation and let us solve it.
X=(3X+2)(3X-2)
We move all terms to the left:
X-((3X+2)(3X-2))=0
We use the square of the difference formula
9X^2+X+4=0
a = 9; b = 1; c = +4;
Δ = b2-4ac
Δ = 12-4·9·4
Δ = -143
Delta is less than zero, so there is no solution for the equation
