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.
How to Solve Quadratic Equations in the Form ax2 + bx + c = 0 with Trinomial factorisationConnor Davidson
Solving for the values of x in a quadratic equation yields 2 values, called the root of the quadratic equation. Quadratic equations always yields 2 values as its roots, or answer. This rises from the fact that the formula to solve a quadratic equation is, x= -b ±√b2- 4ac/(2a) ...

For my assignment on quadratic functions, I have to find the equation (the the form of ax^2+bx+c) for a table of values? The equation would be y = ax^2 + bx + c. Tris Fray Potter said: Homework Equations I know how to use vertex form and change from vertex form to standard...
To find a quadratic from its zeroes, convert the solutions "x=a" and "x=b" to the factors "x−a" and "x−b". Then multiply the factors together.
