Explicación paso a paso:
[tex] {m}^{2} + 5m - 17 = ({m}^{2} + 5m + \frac{25}{4} ) - 17 - \frac{25}{4} \\ = ( {m + \frac{5}{4} )}^{2} - \frac{83}{4} \\ = ((m + \frac{5}{4} ) + \frac{ \sqrt{83} }{2} )((m + \frac{5}{4} ) - \frac{ \sqrt{83} }{2} ) \\ = (m + \frac{5 + 2 \sqrt{83} }{4} )(m + \frac{5 - 2 \sqrt{83} }{4} ) \\ [/tex]
