Denoting the two roots by r 1 and r 2 we distinguish three cases. If the discriminant is zero the fraction converges to the single root of multiplicity two. If the discriminant is not zero, and |r 1 | ≠ |r 2 |, the continued fraction converges to the root of maximum modulus (i.e., to the root with the greater absolute value).
The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.

The solutions –1 and 2 of the polynomial equation x 2 – x + 2 = 0 are the points where the graph of the quadratic function y = x 2 – x + 2 cuts the x-axis. In general, an algebraic equation or polynomial equation is an equation of the form =, or = [a]
The formulation of Lagrange's equations for this system yields six equations in the four Cartesian coordinates x i, y i (i = 1, 2) and the two Lagrange multipliers λ i (i = 1, 2) that arise from the two constraint equations.
[2] In 2013, Adobe bundled a custom version of MathMagic to Adobe Captivate 7 for both macOS and Windows. [3] In September 2014, "MathMagic Lite for Windows" was released. [4] In 2022, the 64-bit versions of MathMagic for macOS were released in Universal binary format for both Intel Macs and M1 Apple silicon Macs. [citation needed]
Vieta's formulas can equivalently be written as < < < (=) = for k = 1, 2, ..., n (the indices i k are sorted in increasing order to ensure each product of k roots is used exactly once). The left-hand sides of Vieta's formulas are the elementary symmetric polynomials of the roots.
Searching for points that are on the line and on the sphere means combining the equations and solving for , involving the dot product of vectors: Equations combined ‖ o + d u − c ‖ 2 = r 2 ⇔ ( o + d u − c ) ⋅ ( o + d u − c ) = r 2 {\displaystyle \left\Vert \mathbf {o} +d\mathbf {u} -\mathbf {c} \right\Vert ^{2}=r^{2 ...
