Question

The discriminant D of x2 - 8 = 0 is ​

Answer 1

$\huge\underline\bold\color{red}\mathfrak{Answer}$

Discriminant = b² - 4ac

In x² - 8 = 0,

a = 1

b = 0

c = - 8

Discriminant, D = 0² - 4 (1)(-8) = 32

32 is the Discriminant of the equation.

Extra info:-

• a is the coefficient of x²
• b is the coefficient of x
• c is the constant

Here the roots will be real and distinct because D>0.

Answer 2

Answer:

D= b sq. - 4ac

=64 - 4*1*0 (Expression will become x square -8-0)

=64-0

=0
