Question

x square - 2x +1 -x +1?

Kindly solve with explanation.​

Answer 1

Answer:

=x^2-2x+1-x+1

=x^2-2x-x+1+1

=x^2-2x-x+2

=x(x-2) -1(x-2)

=(x-1) (x-2) =0

either,

(x-1) =0

so, x=1

or (x-2) =0

so, x=2

hence, 1 and 2 is right answer

Answer 2

Answer:

x

${x }^{2} - 2x + 1 - x + 1 \\ put \: x = 3 \\ . {3 }^{2} - 2 \times 3 + 1 - 3 + 1 \\. 9 - 6 + 1 - 4 \\ .9 - 7 - 4 \\ .9 - 11 \\ .2 \\ therefore \: you \: right \: answeris \: 2$
