Explanation:
I cannot read what equation you wrote.
but it does not matter.
a quadratic equation has always 2 solutions.
as a cubic equation has always 3 solutions.
and so on.
sometimes they can be identical like for 0 = x² (with 0 as solution 2 times).
and sometimes they can be imaginary like in -1 = x².
but there always are 2 solutions for a quadratic equation.
for example with normal numbers :
1 = x²
the solutions are sqrt(1) = ±1 = +1 and -1.
