Question

find the discriminant x(x-2) +1=0​

Answer 1

Answer:

Answer is 0

Step-by-step explanation:

a/q,

x(x-2) +1 = 0

then,

x²- 2x +1 = 0

By using formula,

D = b² - 4ac

D = (-2)² - 4×1×1 = 0 (a=1, b=-2 and c=1)

D = 4 - 4

D = 0, ans...

Answer 2

Answer:

x(x-2)+1=0

x2 -2x+1=0

b2-4ac= (-2)2 -4×1×1

= 4-4

= 0
