What is the discriminant of #x^2-10x+25# and what does that mean?
Solve y = x^2 - 10x + 25 = 0
D = b^2 - 4ac = 100 - 100 = 0.
There is a double root at
The discriminant is zero so there is only one real (as opposed to imaginary) solution for
The discriminant of a quadratic equation is
A discriminant of zero means there is only one real (as opposed to imaginary) solution for
