Solve equation for x

[oondaasta]

I have the following expression:
(3 - 6 * m) ^ 2 + (1 - 4 * m) ^ 2 + (1 - 2 * m) ^ 2 + 1 / 4 + (2 * m - 1) ^ 2 + (4 * m + -3 / 2) ^ 2 + (6 * m - 3) ^ 2
and i create the derivative of it through: derivative(expression, "m");.
And i get the following derivative: 4 * (2 * m - 1) + 8 * (4 * m + -3 / 2) + 12 * (6 * m - 3) + -(12 * (3 - 6 * m)) - 8 * (1 - 4 * m) - 4 * (1 - 2 * m).
Now i set to derivative equal to 0 and then solve for m. How could i do that?

I don't think there is a root finding algorithm yet in mathjs. You could import a function like this https://observablehq.com/@dvd101x/root-finding
