a) Solve for x:
Divide both sides by 4.
Now take the square root of both sides.
or
b) Find the zeros of:
Finding the zeros of this quadratic equation means find the values of x where the parabola intercepts the x-axis, and, of course, at these points, y = 0 or f(x) = 0, so...
Add 12 to both sides.
Divide both sides by 4.
Take the square root of both sides.
