A quadratic equation is of the form ax^2 + bx + c =0, where a, b, and c are real numbers. The most popular method to solve a quadratic equation is to use a quadratic formula that says x = [-b ±√(b2 - 4ac)]/2a.
Standard Form of a Quadratic FunctionThe standard form of a quadratic function is of the form f(x) = ax2 + bx + c, where a, b, and c are real numbers with a ≠ 0.Quadratic Function ExamplesThe quadratic function equation is f(x) = ax2 + bx + c, where a ≠ 0. Let us see...
The Standard Form of a Quadratic Equation looks like this:a, b and c are known values. a can't be 0 x is the variable or unknown (we don't know it yet)Here are some examples:2x2 + 5x + 3 = 0 In this one a=2, b=5 and c=3 x2 − 3x = 0 This one is a little ...
This particular form of a quadratic equation is called standard form. What makes an Equation Quadratic? It is a wonder why the equations are called "quadratic," when the root "quad" tends to mean "four" - shouldn't this apply to fourth-degree equations (incidentally, these are called ...

Standard form: f(x)=ax2+bx+c Factored form:f(x)=a(x+r)(x+s) Vertex form: f(x)=a(x−h)2+k What is the difference between a quadratic equation and a quadratic function? A quadratic equation is polynomial equation of degree 2. It has the form: ax2+bx+c=0 where a ...
Examples of Quadratic Equations Standard Form BACK Zero-Factor Property If a and b are real numbers and if ab =0, then a = 0 or b = 0. BACK Solve the equation (x + 2)(2x - 1)=0 By the zero factor property we know... Since the product is equal to zero then one of the fac...
