Question

the nature of the roots of the quadratic equation x2-2x+1=0 are answer

​

Answer 1

Answer:

roots are real and equal.

Step-by-step explanation:

a=1, b=-2, c=1

now, D=b²-4ac

D= (-2)²-4×1×1

D= 4-4

D= 0

now if D= 0, we know that the roots are real and equal.

Answer 2

Given :

• x² - 2x + 1 = 0

Find :

• The Nature of Roots.

Solution :

Formula Used -

• D = b² - 4ac

Where,

• a = 1
• b = −2
• c = 1

Now,

= (−2)² − 4 × 1 × 1

= 4 − 4

= 0

Therefore :

• The roots are rational and equal.
