Question

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

Answer 1

Answer:

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.

Hope this will help you

Answer 2

Answer:

If it's discriminant is zero.

so it has same two roots.

discriminant= bsquare -4a upon 2a

for general quadratic equation ax^2+bx+c=0
