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:

1. Δ=0 ; roots are real and equal
2. Δ>0 ; roots are real and unequal
3. Δ<0 ; roots are unreal.

• The value of the discriminant is used in the formula method for finding roots of a quadratic equation.
