翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Completing the square ： ウィキペディア英語版 Completing the square In elementary algebra, completing the square is a technique for converting a quadratic polynomial of the form :$ax^2\; +\; bx\; +\; c\backslash ,\backslash !$ to the form : $a(\backslash cdots\backslash cdots)^2\; +\; \backslash mbox.\backslash ,$ In this context, "constant" means not depending on ''x''. The expression inside the parenthesis is of the form (''x'' + constant). Thus :$ax^2\; +\; bx\; +\; c\backslash ,\backslash !$ is converted to : $a(x\; +\; h)^2\; +\; k\backslash ,$ for some values of ''h'' and ''k''. Completing the square is used in * solving quadratic equations, * graphing quadratic functions, * evaluating integrals in calculus, such as Gaussian integrals with a linear term in the exponent * finding Laplace transforms. In mathematics, completing the square is often applied in any computation involving quadratic polynomials. Completing the square is also used to derive the quadratic formula. ==Overview== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Completing the square」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
