What is a quadratic equation?
A quadratic equation is a type of polynomial equation that represents a second-degree algebraic expression. what is quadratic equation? In other words, it's an equation where the highest power of the variable (usually denoted as "x" is squared. The standard form of a quadratic equation is:

ax2 + bx + c = 0

Here, "a," "b," and "c" are constants, and "x" represents the variable you're trying to solve for. The solutions to a quadratic equation are the values of "x" that make the equation true.

Quadratic equations often correspond to parabolic curves when graphed on a coordinate plane. These curves have a distinctive shape, either opening upwards or downwards, depending on the sign of the coefficient "a."

Solving a quadratic equation typically involves factoring, completing the square, or using the quadratic formula, which provides a direct method for finding the solutions. The solutions can be real or complex numbers, depending on the discriminant (the expression inside the square root of the quadratic formula).
