(Algebra: solve quadratic equations) The two roots of a quadratic equation, for example, , can be obtained using the following formula: r1 = (-b + sqrt(b^2 - 4ac) / (2a) and r1 = (-b - sqrt(b^2 - 4ac) / (2a) b^2 - 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots....
