Determine the nature of the roots of the following quadratic equations from their discriminants :
`x^(2)-4x+4=0`

Text Solution

Verified by Experts

The correct Answer is:
The roots are real and equal.
Comparing equation `x^(2)-4x+4=0` with `ax^(2)+bx+c=0`
`a=1,b=4,c=4`
`Delta=b^(2)-4ac=(4)^(2)-4(1)(4)`
=16-16=0
Here, `Delta=0`
