Identify the quadratic form: consider converting to vertex form \( y = a(x-h)^2 + k \) or using \( x = - rac{b}{2a} \) to find the line of symmetry.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
Let's crack this beautiful non-linear system! When a line intersects a circle at 'exactly one point', it means the line is tangent to the circle. Mathematically, this means if we substitute the line's equation into the circle's equation, th...
