How will you verify if a quadratic polynomial has only one zero

a quadratic polynomial cannot have only one zero. there must be two zeroes compulsorily,as it is quadratic. but a same number can be the zeroes with multiplicity. further it can be verified by substituting it in the polynomial's variable.

- plz mark me the brainliest.
