Can someone help me with finding the quadratics of this equation? I tried to do the formula to do it (google it if you havent seen it) but i get a 0 in the squared roots, which is undefined. So how can this one be solved? (if you dont know how to do these question, scroll on and dont try and babble on.)

No, sorry, sqrt doesn't turn a real value into a boolean

it's plus AND minus, not plus OR minus
the curve skims y=0 and is counted twice for reasons later
