completesquare s^2+s+5

解

平方を完成

s^{2} + s + 5

解

(s + \frac{1}{2})^{2} + \frac{19}{4}

解答ステップ

s^{2} + s + 5

次の形式で

s^{2} + s + 5

を書く:

x^{2} + 2 a x + a^{2}

2 a = 1 : a = \frac{1}{2}

加算と減算

(\frac{1}{2})^{2}

s^{2} + s + 5 + (\frac{1}{2})^{2} - (\frac{1}{2})^{2}

x^{2} + 2 a x + a^{2} = (x + a)^{2}

s^{2} + 1 s + (\frac{1}{2})^{2} = (s + \frac{1}{2})^{2}

(s + \frac{1}{2})^{2} + 5 - (\frac{1}{2})^{2}

簡素化

(s + \frac{1}{2})^{2} + \frac{19}{4}
