Step-by-step explanation:

Answer 2

Answer:

Ma'am

let x = m

hence the equation will be

${m}^{2} - 2m - 1 + 2$

= m^2-2m+1

now taking the factors of 1

hence

${m}^{2} - 1m - 1m + 1$

now,

$m(1 - m) - 1(m - 1)$

hence by using the factorisation method we get factors of x

which are

$\sqrt{1 - m}$

and

$\sqrt{1 - m}$

I hope this answer satisfies you

if it is wrong then plz comment me
