Answer:
In quadratic equation D is known as Discriminant.
Step-by-step explanation:
#SomethingXtra
- Discriminant is denoted by 'Δ'.
- For a quadratic equation ax²+bx+c=0, its value is calculated by b²-4ac.
- Discriminant is useful to determine the nature of the roots of a quadratic equation.
- If value of discriminant is:
- Δ=0 ; roots are real and equal
- Δ>0 ; roots are real and unequal
- Δ<0 ; roots are unreal.
- The value of the discriminant is used in the formula method for finding roots of a quadratic equation.
