Question

2. Find the value of
discriminant (b2 - 4ac) of
equation x^2-2x +1 =O​

Answer 1

Answer:

b=(-2)

a =1

c = 1

Step-by-step explanation:

b^2-4ac = discriminant

4-4(1)(1)

=0

so therefore, discriminant for given equation is zero (0)

Answer 2

$\huge\underline\mathrm\red{Answer:-}$

$\mathrm\blue{discriminant:-}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{ {b}^{2} - 4ac }$

$\mathrm\red{Given:-}$

${x}^{2} - 2x + 1 = 0$

$\mathrm{there,a=1,b=-2,c=1}$

$\mathrm\purple{put\:the\: values\:in\: discriminant}$

$\sqrt{ {b}^{2} - 4ac} = \\ \\ \sqrt{ {( - 2)}^{2} - 4 \times 1 \times 1 }$

$= \sqrt{4 - 4}$

$= 2 - 2$

$= 0$
