Question

x^2-4x+4=0 determine nature of roots​

Answer 1

Answer:

2 , 2 (nature is equal and real)

Step-by-step explanation:

First we break it into 2 parenthesis

(x ±   )(x ±   )

The left out terms will sum upto -4 and their product should be +4.

So, we have$(x -2)(x-2)$

equate the to zero and we have $x = 2,2$
