Quadratic equation - Wikipedia
In mathematics, a quadratic equation (from Latin quadratus ' square ') is an equation that can be rearranged in standard form as [1] a x 2 + b x + c = 0, ${\displaystyle a{x}^{2}+bx+c=0\phantom{\rule{0.167em}{0ex}},}$ where the variable x ${\displaystyle x}$ represents an unknown number, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear ...

Quadratic function - Wikipedia
The graph of a real single-variable quadratic function is a parabola. If a quadratic function is equated with zero, then the result is a quadratic equation. The solutions of a quadratic equation are the zeros (or roots) of the corresponding quadratic function, of which there can be two, one, or zero.

Quadratic Function - GeeksforGeeks
Graphing Quadratic Function The graph of the quadratic function is a U-shaped parabola whose direction is either upwards or downwards. Steps to plot a graph of a quadratic function: Find the vertex of the quadratic function. Construct the table for different values of x and substitute them to find the value of the quadratic function f (x), i.e., y.

Introduction to Quadratic Equations - GeeksforGeeks
A quadratic equation is a polynomial equation of degree 2 in one variable. It can have two real roots, one repeated real root, or two complex roots. Its graph is a parabola, which opens upward if a>0 and downward if a<0. 5x2 + x + 2 = 0, x2 = 2x + 3 and 2x2 = 0 are all examples of quadratic equations. The following is a real-life example: A Parabola Standard Form The standard form of a ...
