(36-R)^2+(18-R)^2=R^2

解

(36 - R)^{2} + (18 - R)^{2} = R^{2}

解

R = 90, R = 18

解答ステップ

(36 - R)^{2} + (18 - R)^{2} = R^{2}

拡張

(36 - R)^{2} + (18 - R)^{2} : 2 R^{2} - 108 R + 1620

2 R^{2} - 108 R + 1620 = R^{2}

R^{2}

を左側に移動します

R^{2} - 108 R + 1620 = 0

解くとthe二次式

R_{1, 2} = \frac{- ( - 108 ) \pm ( - 108 ) ^{2} - 4 \cdot 1 \cdot 1620}{2 \cdot 1}

(- 108)^{2} - 4 \cdot 1 \cdot 1620 = 72

R_{1, 2} = \frac{- ( - 108 ) \pm 72}{2 \cdot 1}

解を分離する

R_{1} = \frac{- ( - 108 ) + 72}{2 \cdot 1}, R_{2} = \frac{- ( - 108 ) - 72}{2 \cdot 1}

R = \frac{- ( - 108 ) + 72}{2 \cdot 1} : 90

R = \frac{- ( - 108 ) - 72}{2 \cdot 1} : 18

二次equationの解:

R = 90, R = 18
