Question

Find the value of discriminant of the quadratic equation x2 + 4x 4=0.​

Answer 1

b^2-4ac=0

a=1 , b=4 & c=4

4^2 -4*1*4=0

16-16 =0

They have equal roots

Answer 2

Given,

The quadratic equation x² + 4x + 4 is given.

To find,

We have to find the value of the discriminant of the quadratic equation x² + 4x + 4.

Solution,

The value of the discriminant of the quadratic equation  x² + 4x + 4 is 0.

We can simply find the value of the discriminant of the quadratic equation x² + 4x + 4, by using the formula of the discriminant.

             =  x² + 4x + 4

        D = b² -4ac

         D = (4)² - 4(1)(4)

         D = 16 -16

         D = 0

Since the value of the discriminant is 0, this implies that the quadratic equation has real and equal roots.

Hence, the value of the discriminant of the quadratic equation x² + 4x + 4 is 0.
