There is one solution for this expression:
$color(green)(x=1$

$3x^2–6x+3=0$

We can first factorise the above expression and then proceed towards finding the solutions:

Factorising by splitting the middle term

$3x^2–color(green)(6x)+3=0$

$3x^2–color(green)(3x - 3x)+3=0$

$3x(x-1) - 3(x -1)=0$

$(x-1)$ is common to both terms.

$color(green)((3x-3) (x-1)$ is the factorised form for the expression.

Now we can equate the factors with zero and find the solutions:
$3x-3 = 0 , x=3/3, color(green)(x=1$
$x-1 = 0 , color(green)(x=1$
