Example:
[tex] x^{2} +2x+1=0[/tex]
Factor the given quadratic equation,
[tex](x+1)(x+1)=0[/tex]
Transpose each,
[tex]x=-1[/tex] and [tex]x=-1[/tex]
Example:
[tex] x^{2} -4=0[/tex]
Factor the given quadratic equation,
[tex](x-2)(x+2)=0[/tex]
Transpose each,
[tex]x=2[/tex] and [tex]x=-2[/tex]
I hope you understand my explanation, if not please feel free to ask ^_^
