    remember the general quadratic formula then x = -b/2a will give the line of symmetry. Substitute this value into the original equation to get the max or min. The coefficent of x^2 determines concavity, positive concave up, negative concave down. Last set is to find the roots by solving for x so let\[-x^2 +12x + 3 = 0 \] looks like you'll need the GQF to find x or where the curve cuts the x axis
