4x^2+63x-16=0

解

4 x^{2} + 63 x - 16 = 0

解

x = \frac{1}{4}, x = - 16

+1

十進法表記

x = 0.25, x = - 16

解答ステップ

4 x^{2} + 63 x - 16 = 0

解くとthe二次式

x_{1, 2} = \frac{- 63 \pm 6 3 ^{2} - 4 \cdot 4 ( - 16 )}{2 \cdot 4}

6 3^{2} - 4 \cdot 4 (- 16) = 65

x_{1, 2} = \frac{- 63 \pm 65}{2 \cdot 4}

解を分離する

x_{1} = \frac{- 63 + 65}{2 \cdot 4}, x_{2} = \frac{- 63 - 65}{2 \cdot 4}

x = \frac{- 63 + 65}{2 \cdot 4} : \frac{1}{4}

x = \frac{- 63 - 65}{2 \cdot 4} : - 16

二次equationの解:

x = \frac{1}{4}, x = - 16
