The only problem which can arise is how to implement the algorithm while keeping it general. equations can be solved algebraically, however many cannot be solved, because of the complexity. A quadratic equation has two roots and the roots depend on the discriminant. We can calculate the root of a quadratic by using the formula: x = (-b ± √(b 2-4ac)) / (2a). It means we get one real solution. Suggestions welcome. Here, X is also called a solution of the modular equation. … For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. In the equation ax2+bx+c=0, a, b, and c are unknown values and a cannot be 0. x is an unknown variable. The Math class contains methods for finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions (sin, cos, tan etc. Any linear equation in one variable has the form aX + b = cX + d.
