expand sgn(x^2-16)sqrt(8-2x-x^2)

expand

s g n (x^{2} - 16) 8 - 2 x - x^{2}

n s g x^{2} - x^{2} - 2 x + 8 - 16 n s g - x^{2} - 2 x + 8

Solution steps

s g n (x^{2} - 16) 8 - 2 x - x^{2}

= n s g 8 - 2 x - x^{2} (x^{2} - 16)

Apply the distributive law:

a (b - c) = ab - a c

n s g 8 - 2 x - x^{2} (x^{2} - 16) = n s g 8 - 2 x - x^{2} x^{2} - n s g 8 - 2 x - x^{2} \cdot 16

= n s g 8 - 2 x - x^{2} x^{2} - n s g 8 - 2 x - x^{2} \cdot 16

Simplify

n s g 8 - 2 x - x^{2} x^{2} - n s g 8 - 2 x - x^{2} \cdot 16 : n s g x^{2} - x^{2} - 2 x + 8 - 16 n s g - x^{2} - 2 x + 8

= n s g x^{2} - x^{2} - 2 x + 8 - 16 n s g - x^{2} - 2 x + 8
