Question

The discriminant of the quadratic equation x^2 - 4x + 4 = 0​

Answer 1

Answer:

Discriminant b² - 4ac

(4)² - 4 ( 1 ) ( 4 )

16 - 16

= 0

Hence roots are real and equal

- b/2a , -b/2a

-16/2 = -8/1

Hence roots are -8/1 , -8/1

or -8 and -8

Answer 2

Answer:

Step-by-step explanation:

x² - 4x + 4 = 0

D = b² - 4ac

Here :

b = -4 , c = 4 , a = 1

D = (-4)² - 4 (1)(4)

D = 16 - 16

D = 0

SO THE DICRIMINANT OF X² - 4X + 4 IS ZERO
