The quadratic equation is a second-degree polynomial equation in one variable, usually written in the form:
ax^2 + bx + c = 0
where a, b, and c are constants, and x represents the variable. To solve the equation, you can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
This formula provides the roots of the equation, which are the values of x that satisfy the equation. The quadratic equation is used to solve problems involving parabolic curves and is a fundamental concept in algebra.
The quadratic equation is a polynomial equation of the second degree, which means it contains at least one term with a variable raised to the power of two. The general form of the quadratic equation is:
ax^2 + bx + c = 0
Here, "a", "b", and "c" are coefficients, and "x" is the variable.
To find the solutions to the quadratic equation, you can use the quadratic formula, which is:
x = (-b ± √(b^2 - 4ac))/(2a)
To use the quadratic formula, you need to know the values of the coefficients "a", "b", and "c". By substituting these values into the quadratic formula and simplifying, you can find the solutions for "x". The solutions can be real numbers or complex numbers, depending on the discriminant (the value inside the square root).
