Question

x2-4x+4=0 nature of roots of this eqaution
​

Answer 1

Answer:

x^2-2x-2x+4

Step-by-step explanation:

common x (x-2) -2 (x+2)

(x-2) (x-2)= 0

x=2 x= 2

Answer 2

Answer:

as

d=b²-4ac

putting values

as

a=1

b=-4

c=4

d=(-4*-4)-(4*1*4)

d=16-16

d=0

hence the nature of roots is equal and real roots
