Question

X square -4x+4=0 how to determine the nature of roots of this quadratic equation

Answer 1

Step-by-step explanation:

To determine the nature of roots you have to calculate the value of DETERMINANT (D).

So, D = √(b^2 - 4ac)

D = √(16 -4(1)(4))

D = √(16 - 16)

D = 0

Now,

If D > 0 , then roots are real & distinct.

If D <0 , then roots are imagenary.

If D = 0 , then roots are real but coincident.

Hence, nature of roots of given quadratic is real and same (coincident).
