In mathematics, a quadratic equation (from Latin quadratus ' square ') is an equation that can be rearranged in standard form as [1] where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.)
Quadratic Equation in Standard Form: ax 2 + bx + c = 0; Quadratic Equations can be factored; Quadratic Formula: x = −b ± √(b 2 − 4ac) 2a; When the Discriminant (b 2 −4ac) is: positive, there are 2 real solutions; zero, there is one real solution; negative, there are 2 complex solutions
Quadratics are the polynomial equation which has highest degree of 2. Also, called quadratic equations. Learn quadratic formulas, solution to quadratic equations with the example at BYJU'S.
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax 2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Gain more insight into the quadratic formula and how it is used in quadratic equations. The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math.
For example, equations such as 2x2 + 3x − 1 = 0 and x2 − 4 = 0 are quadratic equations. They are used in countless ways in the fields of engineering, architecture, finance, biological science, and, of course, mathematics. Often the easiest method of solving a quadratic equation is factoring.
We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.

Feb 14, 2022 · To use the Quadratic Formula, we substitute the values of \(a,b\), and \(c\) from the standard form into the expression on the right side of the formula. Then we simplify the expression. The result is the pair of solutions to the quadratic equation. Notice the Quadratic Formula (Equation \ref{quad}) is an equation.
A quadratic equation is a polynomial equation with degree two. In other words, it is an equation of the form \ ( ax^2 + bx + c =0 \), where \ ( a \), \ (b\) and \ (c\) are real numbers and \ (a\neq 0\). Solving by Factoring. Main Article: Factoring Polynomials. We can solve quadratics using factoring and the zero product property.
