Question

x2-6x+5=0 con fórmula cuadrática​

Answer 1

Explicación paso a paso:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4(a)(c)} }{2a} \\ x = \frac{6 + - \sqrt{36 - 4(1)(5)} }{2} = \frac{6 + - \sqrt{36 - 20} }{2} \\ x = \frac{6 + - \sqrt{16} }{2} \\ x = \frac{6 + - 4}{2} \\ x = \frac{6 + 4}{2} = \frac{10}{2} = 5 \\ x = \frac{6 - 4}{2} = \frac{2}{2} = 1$
