Question

Find the value of the discriminas (∆) for the quadratic equation x square - 6x- 5 = 0​

Answer 1

Step-by-step explanation:

As

Disc=b^2-4ac

here

a=1

b=-6

c=-5

putting these values

so

Disc=(1^2)-4(-6)(-5)

=1-4(30)

=1-120

Disc=-119

Answer 2

Answer:

56

Step-by-step explanation:

Discriminant(d) = b²-4ac

here, a = 1

         b = -6

         c = -5

Now put these values ,

d = (-6)² - 4(1)(-5)

  =  36 - (-20)

  = 36 + 20

  = 56
