Physically what does it mean if the solution of quadratic equation are complex numbers?
so the roots are not real, this means that the curve does not cut the x axis
is it it have no solution
complex solutions are solutions
for example \[x^2+1=0\] \[x=\frac{-0\pm\sqrt{0^2-4(1)(1)}}{2}\]\[x=\frac{\pm2i}2=\pm i\] if we plot \[y(x)=x^2+1=0\] |dw:1354618723421:dw|
It means you have entered the 5th dimension. Watch out for aliens.
