3x^2-60x+100=0

解

3 x^{2} - 60 x + 100 = 0

解

x = \frac{10 ( 3 + 6 )}{3}, x = \frac{10 ( 3 - 6 )}{3}

+1

十進法表記

x = 18.16496 \dots, x = 1.83503 \dots

解答ステップ

3 x^{2} - 60 x + 100 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 60 ) \pm ( - 60 ) ^{2} - 4 \cdot 3 \cdot 100}{2 \cdot 3}

(- 60)^{2} - 4 \cdot 3 \cdot 100 = 206

x_{1, 2} = \frac{- ( - 60 ) \pm 20 6}{2 \cdot 3}

解を分離する

x_{1} = \frac{- ( - 60 ) + 20 6}{2 \cdot 3}, x_{2} = \frac{- ( - 60 ) - 20 6}{2 \cdot 3}

x = \frac{- ( - 60 ) + 20 6}{2 \cdot 3} : \frac{10 ( 3 + 6 )}{3}

x = \frac{- ( - 60 ) - 20 6}{2 \cdot 3} : \frac{10 ( 3 - 6 )}{3}

二次equationの解:

x = \frac{10 ( 3 + 6 )}{3}, x = \frac{10 ( 3 - 6 )}{3}

y^{2} - y - 2 y = 0

solvefor x,y^2-x^2+1=50

so l v e f or x, y^{2} - x^{2} + 1 = 50

solvefor x,x^2+2x+1=m^2

so l v e f or x, x^{2} + 2 x + 1 = m^{2}
