Question

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

Answer 1

Check if b^2 – 4ac = 0, If it would be 0 then the quadratic polynomial has only 2 zero but they are equal to each other or we can say 1 zero.

Here b is the coefficient of the variable with degree 1, a is the coefficient of the variable with degree 2 and c is the constant term.
