Question

find the determinant and the nature of the roots of a=1 b=5 c=4​

Answer 1

Step-by-step explanation:

discriminat of roots formula: b^2-4ac

here, a=1, b= 5, c= 4

so, by putting the values in the given formula...

= (5)^2-4(1)(4)

= 25-16= 9

so, discriminat= 9

9>0

so, roots are real....

Answer 2

Step-by-step explanation:

Discriminant = b^2 - 4ac

= (5)^2 - 4(1)(4)

= 25 - 16

= 9

As the D is greater than 1

the roots are real and distinct
