What is a Quadratic Equation?
Before we dive into the specifics of 4x ^ 2 – 5x – 12 = 0, let’s revisit the basics. A quadratic equation is a second-degree polynomial equation, and its standard form is ax² + bx + c = 0. Here, a, b, and c are constants.
A quadratic equation is a second-order polynomial equation in a single variable, usually written in the standard form:
ax2+ bx + c = 0
Here, x represents the variable, and a, b, and c are coefficients, with a ≠ 0. The solutions to the quadratic equation, known as roots, can be found using the quadratic formula:
The term inside the square root, b^2 – 4ac, is called the discriminant. The nature of the roots depends on the value of the discriminant:
- If b2 – 4ac > 0, the equation has two distinct real roots.
- If b2– 4ac = 0, the equation has one real root (a repeated root or double root).
- If b2– 4ac < 0, the equation has two complex (conjugate) roots.
Quadratic equations often arise in various mathematical and scientific applications, and their solutions can be used to find the points where the quadratic expression equals zero.
