What is the discriminant of #4x^2-4x+1=0# and what does that mean?
The discriminant of an equation tells the nature of the roots of a quadratic equation given that a,b and c are rational numbers.
The discriminant of a quadratic equation
The discriminant actually tells you the nature of the roots of a quadratic equation or in other words, the number of x-intercepts, associated with a quadratic equation.
Now we have an equation;
Now compare the above equation with quadratic equation
Hence the discriminant (D) is given by;
Therefore the discriminant of a given equation is 0.
Here the discriminant is equal to 0 i.e.
