3q^2-110q+900=0

解

3 q^{2} - 110 q + 900 = 0

解

q = \frac{5 ( 11 + 13 )}{3}, q = \frac{5 ( 11 - 13 )}{3}

+1

十進法表記

q = 24.34258 \dots, q = 12.32408 \dots

解答ステップ

3 q^{2} - 110 q + 900 = 0

解くとthe二次式

q_{1, 2} = \frac{- ( - 110 ) \pm ( - 110 ) ^{2} - 4 \cdot 3 \cdot 900}{2 \cdot 3}

(- 110)^{2} - 4 \cdot 3 \cdot 900 = 1013

q_{1, 2} = \frac{- ( - 110 ) \pm 10 13}{2 \cdot 3}

解を分離する

q_{1} = \frac{- ( - 110 ) + 10 13}{2 \cdot 3}, q_{2} = \frac{- ( - 110 ) - 10 13}{2 \cdot 3}

q = \frac{- ( - 110 ) + 10 13}{2 \cdot 3} : \frac{5 ( 11 + 13 )}{3}

q = \frac{- ( - 110 ) - 10 13}{2 \cdot 3} : \frac{5 ( 11 - 13 )}{3}

二次equationの解:

q = \frac{5 ( 11 + 13 )}{3}, q = \frac{5 ( 11 - 13 )}{3}
