I really don't understand why this is a thing

If the discriminant is less than 0, then there are roots, just no *real* roots. Let's say there was √-9. It would be 3i.

Are roots the same as solutions?? Besides that everything made sense. Thanks!

you have move the -6 to the left side of the equation so add positive 6 to both sides...

The second example sum is -8, not 40. So the answer for 3x^2-4x-2=0 is “ There are no roots “ rather than “ Two distinct real roots”.

what if its like -8x^2-2x-15=-6 how do u do that if it equals a number other than zero?

so if it is a perfect square then how many roots are there

So, say the equation is equal to -8. Would I have to make it equal to 0? Or doesnt it matter...
