v2.c17.s9.17

If there be r terms on the left hand side, then on rationalisation, we shall have an equation of 2rth degree in x. By proper substitutions, the equation will be ultimately reduced to a quadratic equation of the form $X - A√BX = R,$ whose solution is given by Mahâvîra as $X = (A + √(A² + 4R/B))/2² × B.$
