- CompleteSquare[ <Quadratic Function> ]
- Returns the quadratic function in vertex form: a(x-h)^2+k.
- Example:
CompleteSquare[x^2 - 4x + 7]yields the function f(x) = (x - 2)2 + 3.
CAS Syntax
- CompleteSquare[ <Quadratic Function> ]
- Returns the quadratic function in the form: a(x-h)^2+k.
- Example:
CompleteSquare[x^2 - 4x + 7]yields (x - 2)2 + 3.
Comments
Article Completing the square on wikipedia shows how can this be useful in describing and plotting quadratic functions.
