6) with γ = α 2 + β 2 , γ = α 2 + β 2 . 7) shows that L is the radical axis of C, D. 7 Let C, D be non-concentric circles. We claim that the centres of the circles λC + µD all lie on the centre line, the line M joining the centres of C, D. 5 Pencils of Circles 29 constants s, t with s + t = 1 by s= λ , λ+µ t= µ . λ+µ With these choices the canonical form for λC + µD is given by the expression x 2 + y 2 − 2(sα + tα )x − 2(sβ + tβ )y + (sc + tc ). It follows that its centre is the point s(α, β) + t (α , β ) on the parametrized line joining the centres (α, β), (α , β ) of C, D.

For instance, the line joining P = (2, −1), Q = (2, −2) is 3x + 4y − 2 = 0, having direction vector P − Q = (−4, 3). 5 Let P, Q be distinct points. A point Z is equidistant from P, Q when the distances from Z to P, Q are equal. That is equivalent to 18 The Euclidean Plane P Z Q Fig. 3. The perpendicular bisector |P − Z |2 = |Q − Z |2 . The set of points equidistant from P, Q is called the perpendicular bisector of the line segment joining P, Q. ) We claim that the perpendicular bisector is a line.

13) gives three linear equations in α , β , γ b = ββ , 2h = αβ + α β, 2 f = βγ + β γ . The determinant of the 3 × 3 matrix of coefficients is −β 3 , hence non-zero. By linear algebra there is a unique solution α , β , γ , yielding a unique line L . It remains to note that J (x) is uniquely determined by the requirement that Q(x, 0) = L(x, 0)L (x, 0) + J (x). Assuming instead that L is not parallel to the x-axis, we obtain a similar conclusion, with J (x) replaced by a quadratic K (y). The only difference in the proof is that the line L is determined by equating the coefficients of x 2 , x y, x.
