Write the solution set of equation x² - 4x + 5 = 0 in roster from.

The set will have the elements as the solutions of 

$\sf \: x {}^{2} −4x−5=0</p><p></p><p>$

$\sf \: =>x {}^{2} −5x+x−5=0</p><p></p><p>$

$\sf=>x(x−5)+1(x−5)=0$

$\sf \: =>(x=5,−1)$

$\pink{ \sf \: So, the \: set \: is \: ( { 5,−1 } \: )}$
