Finally, there are two methods to use, depending on if the given quadratic equation can be factored or not.
1.- The first one is the new Diagonal Sum Method, recently presented in book titled: "New methods for solving quadratic equations" (Trafford 2009). This method directly gives the two roots in the form of two fractions, without having to factor it. The innovative concept of this new method is finding 2 fractions knowing their product (c/a) and their sum (-b/a). This new method is applicable to any quadratic equation that can be factored. It can replace the existing trial-and-error factoring method since this last one contains too many more permutations. In general, it is hard to tell in advance if a given quadratic equation can be factored. However, if the new method fails to get the answers, then you can positively conclude that this equation can not be factored. Consequently, the quadratic formula must be used in solving. We advise students to always try to solve the given equation by the new method first.
If the student gets conversant with this method, it usually take less than 2 trials to get answers.
2. the second one uses the quadratic formula that students can find in any algebra book. This formula must be used for all quadratic equations that can not be factored.

What does it mean to solve a system of quadratic equations?
Solving a system of quadratic equations involves finding the values of the variables that satisfy all equations in the system simultaneously. This typically requires identifying the points of intersection between the curves represented by the quadratic equations on a graph. The solutions can be real or complex numbers and may include multiple pairs of values, depending on the nature of the equations. Techniques for solving these systems include substitution, elimination, or graphical methods.
How do you solve imaginary equations?
The answer depends on the nature of the equation. Just as there are different ways of solving a linear equation with a real solution and a quadratic equation with real solutions, and other kinds of equations, there are different methods for solving different kinds of imaginary equations.

Why were quadratic problems important to Greek mathematicians?
Quadratic problems were significant to Greek mathematicians because they represented a critical advancement in understanding geometric relationships and algebraic reasoning. They were often framed in terms of geometric constructions, leading to the development of methods for solving equations that laid the groundwork for later mathematical exploration. Additionally, solving quadratic problems contributed to the Greeks' pursuit of rigor in mathematics, emphasizing logical deduction and proof, which became foundational to the discipline.

There are two methods of intersection?
The two methods of intersection typically refer to geometric and algebraic approaches. The geometric method involves graphing the equations and visually identifying the points where they intersect. The algebraic method involves solving the equations simultaneously, either by substitution or elimination, to find the exact coordinates of the intersection points. Each method has its advantages depending on the context and complexity of the equations involved.
