Question

Determine whether the given values of x is a root of given equation or not: x² - 2x + 1 =0, x=1
​

Answer 1

Answer:

$x = 1$

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

${(1)}^{2} - 2(1) + 1$

$1 - 2 + 1$

$1 + 1 - 2$

$2 - 2$

$0$

As on solving the result is coming 0 So, value of x is a root of the given polynomial.

Hope it helps.

Answer 2

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

$({1})^{2} - 2(1) + 1 = 0$

$1 - 2 + 1 = 0$

$2 - 2 = 0$

$0 = 0$
