Question

if the discriminant of quadratic equation B square minus 4 AC is equal to zero then roots are what​

Answer 1

Step-by-step explanation:

Real and Equal

Step-by-step explanation:

For a quadratic equation ax² + bx + c =0 we have its two roots α and β

If we calculate its determinant which can be calculated by the formula

b²-4 ac = 0 and its answer comes equal to zero

then it means that it have real and equal roots

Real roots:

Roots does not have an imaginary value in them

Equal Roots:

They both will be equal to each other which means that

α  = β and their difference would be equal to zero
