x^2+x=50

解

x^{2} + x = 50

解

x = \frac{- 1 + 201}{2}, x = \frac{- 1 - 201}{2}

+1

十進法表記

x = 6.58872 \dots, x = - 7.58872 \dots

解答ステップ

x^{2} + x = 50

50

を左側に移動します

x^{2} + x - 50 = 0

解くとthe二次式

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 \cdot 1 \cdot ( - 50 )}{2 \cdot 1}

1^{2} - 4 \cdot 1 \cdot (- 50) = 201

x_{1, 2} = \frac{- 1 \pm 201}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 1 + 201}{2 \cdot 1}, x_{2} = \frac{- 1 - 201}{2 \cdot 1}

x = \frac{- 1 + 201}{2 \cdot 1} : \frac{- 1 + 201}{2}

x = \frac{- 1 - 201}{2 \cdot 1} : \frac{- 1 - 201}{2}

二次equationの解:

x = \frac{- 1 + 201}{2}, x = \frac{- 1 - 201}{2}

completesquare 2x^2+5x+2=0

co m pl e t es q u a re 2 x^{2} + 5 x + 2 = 0

x (x + 7) = 30

X^{2} = 9

(3x-5)^2+(2x-7)^2=(5x-3)^2

(3 x - 5)^{2} + (2 x - 7)^{2} = (5 x - 3)^{2}
