Answer 1

Step-by-step explanation:

$(m - 1) = \frac{8}{m + 1} \\ (m - 1)(m + 1) = 8 \\ {m}^{2} - 1 = 8 \\ {m}^{2} = 9 \\ m = 3 \: \: \: or \: m = - 3$

hope this will help u......

Answer 2

$</p><p></p><p>\Rightarrow \quad \left( m - 1 \right) = \frac{8}{ \left( m + 1 \right) } \\ \\ \Rightarrow \quad \left( m + 1 \right) \left( m - 1 \right) = 8 \\ \\ \Rightarrow \quad m^{2} - 1^{2} = 8 \\ \\ \Rightarrow \quad m^{2} = 8 + 1 \\ \\ \Rightarrow \quad m = \sqrt{9} \\ \\ \Rightarrow \quad m = \pm 3 </p><p></p><p>$
