Question

If x2-2x+1=0 then x+1/x is

Answer 1

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

$x + 1 \div x = 1 + 1 = 2$

Answer 2

Answer:

Step-by-step explanation:

> x² - 2x + 1 = 0

by mid term splitting.

=> x² - x - x + 1 = 0

=> x ( x - 1 ) - 1 ( x - 1 ) = 0

=> ( x - 1 ) ( x - 1 ) = 0

=> x - 1 = 0 or x - 1 = 0

we get x = 1 from both

=> x = 1

put x = 1 in below

=> x + 1/x

=> 1 + 1/1

=> 1 + 1

=> 2

Hence, x + 1/x = 2

i hope it helps you.
