Question

for equation ax²+bx+c=0 value are as a=√5,b=-1,c=-√5. find the value of didcriminant​

Answer 1

Answer:

D = 21

Step-by-step explanation:

Replacing a, b, c in the equation: √5x² - x - √5 = 0

D = b² - 4ac = (- 1)² - 4 (√5) (- √5) = 1 + 4(5) = 1 + 20 = 21

Answer 2

Answer:

21

Step-by-step explanation:

a= √5  ,  b= -1   , c= -√5

discriminant = b^2 - 4ac

(-1)^2 - 4 * √5 * (-√5)

1 - 4 * (-5)

1 + 20

=20
