Normally a quadratic equation will graph out into a parabola. The standard form is f(x)=a(x-h)2+k
Standard Form Quadratic Equation Quadratic equations can be written in the form ax2 + bx + c = 0 where a, b, and c are real numbers with a 0. Standard form for a quadratic equation is in descending order equal to zero. BACK Examples of Quadratic Equations Standard Form BACK Zero-...

Example 3: Write the quadratic function f(x) = (x-12)(x+3) in the general form ax2 + bx + c. Solution: We have the quadratic function f(x) = (x-12)(x+3). We will just expand (multiply the binomials) it to write it in the general form. f(x) = (x-12)(x+3) = x...
When the numerator and denominator are co-prime then it is considered to be written in the standard form. But for this, both the numbers shouldn’t have a common factor of 1 For example. 5/6, 11/12. What is the standard form of the quadratic function? The general way of writing the...
Factored Form of the Quadratic Function: y = a(x-r)(x-s) or f(x) = a(x-r)(x-s) ex) x-intercepts (2 , 0) and ( 4 , 0) or x-int = 2 and 4 (assumption is y = 0) Notice: 2 and 4 are the values subtracted in the equation **So, in the factored form “r” an...
Standard Form is useful because a lot of times as it's helpful to find the x and y intercepts. And it also gets to be useful once you start studying quadratics which is when you have x squared. However most of the time people like to use equations that are either in point slope fo...
Finally, convert the terms inside parentheses to a squared unit of the form (x – h)^2. The value of h is equal to half the coefficient of the x term. For example, 2(x^2 – 14x + 49) – 88 becomes 2(x – 7)^2 – 88. The quadratic equation is now in vertex form. Graphi...
Standard form to represent a quadratic equation is as mentioned below: ax2+bx+c=0 How to write the quadratic equation if the roots are already given : Let the roots of the above mentioned equation be α andβ Then we can write the same equation as mentioned below: ...
Answer to: Write the quadratic function in standard form: f(x) = (x - 3)^2 By signing up, you'll get thousands of step-by-step solutions to your...
