Question

For the following equation
find the value of the
discriminant.
V2x² – 5x + V2 = 0
​

Answer 1

Answer:

Step-by-step explanation:

Compare √5x² - x - √5 = 0 with ax²+bx+c = 0,

we get

a = √5 , b = -1 , c = -√5

discreaminant ( D ) = b² - 4ac

D = ( -1 )² - 4 × √5 × ( - √5 )

D = 1 + 4 × 5

D = 1 + 20

D = 21

Therefore ,

discreaminant ( D ) = 21
