190x-x²=67 paso a paso porfavor​

Answer 1

$190x-x²=67 \\ 190x - {x}^{2} - 67 = 0 \\ - {x}^{2} + 190x - 67 = 0 \\ {x}^{2} - 190x + 67 = 0 \\ x = \frac{ - ( - 190)± \sqrt{( - 190) {}^{2} - 4 \times 1 \times 67 } }{2 \times 1} \\ x = \frac{190± \sqrt{36100 - 268} }{2} \\ x = \frac{190±2 \sqrt{8958} }{2} \\ x = \frac{190 + 2 \sqrt{8958} }{2} \\ x = \frac{190 - 2 \sqrt{5958} }{2} \\ x = 95 + \sqrt{8958} \\ x = 95 - \sqrt{8958} = \\ \\ rpta1 = : x_{1} = 95 - \sqrt{9858} \\ rpta2 : x_{2} = 95 + \sqrt{8958} \\ \\respuestas \: en \: decimal: \\ \\ x_{1} = 0.353288 \\ x_{2} = 189.64671$
