No, they used Square Roots. As you should know, an equation usually has as many solutions as its highest degree.
For example, X^2 = 1 has two solutions, -1 and 1. Does this mean -1 and 1 are equal though?
Kimi wa ne tashika ni ano toki watashi no soba ni ita
Itsudatte itsudatte itsudatte
Sugu yoko de waratteita
Nakushitemo torimodosu kimi wo
I will never leave you
