expand (Sgn(x^2-1))sqrt(x-1)+1

expand

(S g n (x^{2} - 1)) x - 1 + 1

n S g x^{2} x - 1 - n S g x - 1 + 1

Solution steps

(S g n (x^{2} - 1)) x - 1 + 1

Remove parentheses:

(a) = a

= S g n (x^{2} - 1) x - 1 + 1

= n S g (x^{2} - 1) x - 1 + 1

Expand

S g n x - 1 (x^{2} - 1) : n S g x^{2} x - 1 - n S g x - 1

= n S g x^{2} x - 1 - n S g x - 1 + 1

x y^{'} (x) + (1 + x) y
