Quadratic EquationA quadratic equation is an equation of the second degree, meaning it contains a term with the square of a variable. The general form of a quadratic equation is:
```
ax² + bx + c = 0
```
where a, b, and c are constants and a ≠ 0.
Solving Quadratic Equations
There are several methods for solving quadratic equations, including:
1. Factoring:
If the quadratic equation can be factored into two linear factors, it can be solved by setting each factor equal to zero and solving for the variable. For example, if:
```
x² - 5x + 6 = 0
```
can be factored as:
```
(x - 2)(x - 3) = 0
```
then the solutions are x = 2 and x = 3.
2. Completing the Square:
This method involves adding and subtracting a constant to the quadratic equation to create a perfect square trinomial. The square root of the perfect square can then be taken to solve for the variable.
3. Quadratic Formula:
The quadratic formula is a general formula that can be used to solve any quadratic equation:
```
x = (-b ± √(b² - 4ac)) / 2a
```
where a, b, and c are the coefficients of the quadratic equation.
Nature of the Roots
The discriminant of a quadratic equation, which is b² - 4ac, determines the nature of the roots:
* Positive discriminant: Two distinct real roots
* Zero discriminant: One real root (a double root)
* Negative discriminant: No real roots (two complex roots)
Applications of Quadratic Equations
Quadratic equations have numerous applications in various fields, including:
* Projectile motion
* Circuit analysis
* Optimization problems
* Modeling parabolic curves
* Solving geometric problems
