In mathematics, a quadratic equation is a polynomial equation in which the highest exponent of the variable is 2 and that can be put in the form ax2 + bx + c = 0, where a, b, and c are constants. We can solve quadratic equations using a special formula called the quadratic formula....
Find the quadratic function which passes through the vertex: (3, -2) and the point: (7, 6). What are the coordinates of the vertex for f(x) = 3x^{2} + 6x + 3? What is the formula for the vertex of a parabola? The equation f(x) = 4x^2 - 16x + 9 represen...
Regardless of what the quadratic function is expressing, whether it be a positive or negative parabolic curve, every quadratic formula shares eight core characteristics. y=ax2 +bx+c, whereais not equal to 0 The graph this creates is a parabola -- a u-shaped figure. The parabola will open ...

Let r1 and r2 be the integer zeroes of the quadratic. Since the coefficient of the x2 term is 1, the quadratic can be written as (x−r1)(x−r2)=x2−(r1+r2)x+r1r2. By comparing this with x2−ax+2a, r1+r2=a and r1r2=2a. Plugging the first equation in the second, ...
In mathematics, a function is typically represented using notation, such as "f(x)", where "f" is the name of the function and "x" is the input variable. The function can be defined explicitly, with a direct expression or formula, or implic...
