completesquare s^2+s+2

解

平方を完成

s^{2} + s + 2

解

(s + \frac{1}{2})^{2} + \frac{7}{4}

解答ステップ

s^{2} + s + 2

次の形式で

s^{2} + s + 2

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

簡素化

(s + \frac{1}{2})^{2} + \frac{7}{4}

5 x^{2} = 2 x + 3

(150)^2=(x)^2+(3x+15)^2

(150)^{2} = (x)^{2} + (3 x + 15)^{2}

6 x^{2} - 10 x + 5 = 0

9 v^{2} = 30 v - 25

solvefor x,x^2+3y^2-6x+15y+84=0

so l v e f or x, x^{2} + 3 y^{2} - 6 x + 15 y + 84 = 0
