What are quadratic equations?
A quadratic equation is a second-degree polynomial equation in a single variable, usually written in the form ax^2 + bx + c = 0, where a, b, and c are constants.
In simpler terms, a quadratic equation is an equation that can be written in the form of a quadratic function. It involves the variable raised to the power of two, hence the term “second-degree.” Quadratic equations are common in algebra and have various applications in mathematics, physics, engineering, and other fields.
Quadratic equations often have two solutions or roots, which can be real or complex numbers. These solutions can be found using various methods, such as factoring, completing the square, or by using the quadratic formula.
Quadratic equations are used to model a wide range of real-life situations, including projectile motion, optimization problems, and finding the dimensions of geometric shapes. They play a significant role in solving problems involving parabolas, which are U-shaped curves that can be described by quadratic functions.
In conclusion, quadratic equations are fundamental mathematical equations that involve a second-degree polynomial function. They have various applications and are essential in solving problems related to parabolas and other real-life situations. Understanding and solving quadratic equations is an important skill in mathematics and many other fields.
Definition of quadratic equations
A quadratic equation is a polynomial equation of the second degree. It involves a variable raised to the power of two, and may also include other terms such as a constant and a linear term. The general form of a quadratic equation is:
ax^2 + bx + c = 0
Here, a, b, and c are coefficients, and x is the unknown variable. The coefficient a must be nonzero, otherwise the equation would become linear.
The solutions to a quadratic equation can be found using various methods, such as factoring, completing the square, or using the quadratic formula:
x = (-b ± √(b^2 – 4ac)) / 2a
Quadratic equations have a variety of applications in mathematics, physics, engineering, and other fields. They are used to model various real-life situations, such as the motion of objects under the influence of gravity, the shape of projectiles, and the behavior of electrical circuits.

- 3x^2 – 7x + 2 = 0: This quadratic equation cannot be easily factored, so it can be solved using the quadratic formula: x = (-b ± sqrt(b^2 – 4ac)) / 2a. Plugging in the values, we get x = (7 ± sqrt(49 – 24)) / 6, which simplifies to x = (7 ± sqrt(25)) / 6. The solutions are x = 1 and x = 2/3.
- 2x^2 – 4x + 2 = 0: This quadratic equation can be factored as 2(x – 1)^2 = 0, resulting in a double root of x = 1.
