Answer:
Your answer is option d.
Step-by-step explanation:
x2-4x+4=0
x2-2x - 2x + 4 =0
x( x-2) -2(x-2) =0
(x-2) (x-2) =0
SO, (x-2) =0 or (x-2) =0
So, x=2 or x=2.
Answer:
Option (d) 2,2 is the correct answer.
Step-by-step explanation:
=> x^2 - 4x + 4
By splitting the middle term, we get,
=> x^2 - 2x - 2x + 4
=> (x^2 - 2x) (-2x + 4)
=> x(x - 2) -2(x - 2)
=> (x - 2) (x - 2)
Therefore,
x - 2 = 0, x - 2 = 0
x = 2, x = 2
