Question

the discriminal of quadratic equation x²-2x+1= 0 of the value will be:

Answer 1

Discriminant (D) = b^2 - 4ac

= (-2)^2 - 4(1)(1)

= 4 - 4

= 0

Hence, the discriminant of quadratic equation x²-2x+1= 0 of the value will be zero.

Answer 2

Answer:

$\bf \huge given : -$

★x²-2x+1=0

★a=1

★b=-2

★c=1

$\bf \huge \green{formula \: used \: = {b}^{2} - 4ac}$

$\bf \huge \implies{x = {b}^{2} - 4ac}$

$\bf \huge \implies{ {( - 2)}^{2} - 4 \times 1 \times 1}$

$\bf \huge \implies \: 4 - 4$

$\bf \huge \implies \: 0$
