Pros:
There are many real life situations in which the relationship between two variables is quadratic rather than linear. So to solve these situations quadratic equations are necessary.
There is a simple equation to solve any quadratic equation.
Cons:
Pupils who are still studying basic mathematics will not be told how to solve quadratic equations in some circumstances - when the solutions lie in the Complex field.

What are the roots of the quadratic equation below?
That depends on the equation.
How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
What is an equation that can be used in quadratic formula completing the square and factoring?
A quadratic equation.
If the discriminant of a quadratic equation is -4 how many solutions does the equation have?
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.
Which the easy way the method of factoring or the solving the quadratic equation?
By knowing how to use the quadratic equation formula.
