Is it okay to mix the types of brackets you use when writing out a solution to help make it a bit clearer?
For example:
If I was completeing the square with:
$$ 3x^{2} + 5x -2 = 0 $$
I would factor out the 3 onto square brackets like this:
[itex]3 \left[x^{2} + \frac{5}{3}x - \frac{2}{3} \right] = 0 [/itex]
Then do my competing the square with round brackets:
$$ 3 \left[ \left( x + \frac{5}{6} \right)^{2} -\left(\frac{5}{6}\right)^{2} - \frac{2}{3} \right] = 0 $$
