Mathwords: Discriminant of a Quadratic. The number D = b2 – 4ac determined from the coefficients of the equation ax2 + bx + c = 0. The discriminant reveals what type of roots the equation has.

Answer 2

Answer:

D/Δ=b^2-4ac

Step-by-step explanation:

a quadratic equation is by the general formula - ax^2 +bx+c=0

determinant is used to find the nature of the roots of the quadratic equations.

if,

b^2-4ac>0

then,

the roots are real and unequal

if, b^2-4ac<0

then,

the roots are complex i.e imaginary i.e not real

if,

b^2-4ac=0

then,

the roots are real and equal.
