Bijaganita (IAST: Bījagaṇita) was treatise on algebra by the Indian mathematician Bhāskara II. It is the second volume of his main work Siddhānta Shiromani ("Crown of treatises") alongside Lilāvati, Grahaganita and Golādhyāya.
Meaning The title of the work, bījagaṇita, which literally translates to "mathematics (gaṇita) using seeds (bīja)", is one of the two main branches of mediaeval Indian mathematics, the other being pātīgaṇita, or "mathematics using algorithms". Bījagaṇita derives its name from the fact that "it employs algebraic equations (samīkaraṇa) which are compared to seeds (bīja) of plants since they have the potentiality to generate solutions to mathematical problems."
Contents The book is divided into six parts, mainly indeterminate equations, quadratic equations, simple equations, surds. The contents are:
Introduction On Simple Equations On Quadratic Equations On Equations involving indeterminate Questions of the 1st Degree On Equations involving indeterminate Questions of the 2nd Degree On Equations involving Rectangles In Bijaganita Bhāskara II refined Jayadeva's way of generalization of Brahmagupta's approach to solving indeterminate quadratic equations, including Pell's equation which is known as chakravala method or cyclic method. Bijaganita is the first text to recognize that a positive number has two square roots
