Formula of Vertex to Standard Form Calculator

To understand the functionality of the Vertex to Standard Form Calculator, it is crucial to grasp the underlying formula that governs the conversion process:

1. Identify the vertex coordinates: The vertex form of a quadratic equation is given by:plaintextCopy codey = a(x - h)² + k where (h,k) represent the coordinates of the vertex.
2. Expand the squared term: Multiply the “a” term outside the parenthesis with the expression inside the parenthesis:plaintextCopy codey = a(x² - 2hx + h²) + k
3. Distribute the “a” term: Multiply “a” with each term inside the parentheses:plaintextCopy codey = ax² - 2ahx + ah² + k
4. Compare with standard form: The standard form of a quadratic equation is:plaintextCopy codey = ax² + bx + c By comparing the two forms, you can see that:
   • The coefficient of the x² term (a) remains the same.
   • The coefficient of the x term (b) becomes −2ah.
   • The constant term (c) becomes ah2+k.

Therefore, to convert from vertex form to standard form, you simply substitute the above values for �b and �c in the standard form equation.
