expand (x+xsqrt(u^2-1))xdu

expand

(x + x u^{2} - 1) x d u

x^{2} d u + x^{2} d u u^{2} - 1

Solution steps

(x + x u^{2} - 1) x d u

= x (x + x u^{2} - 1) d u

Apply the distributive law:

a (b + c) = ab + a c

a = x d u, b = x, c = x u^{2} - 1

= x d ux + x d ux u^{2} - 1

= xx d u + xx d u u^{2} - 1

Simplify

xx d u + xx d u u^{2} - 1 : x^{2} d u + x^{2} d u u^{2} - 1

= x^{2} d u + x^{2} d u u^{2} - 1

(1 - 4 1)

(1 + 2 x + 3 x^{2})^{5}

(x \cdot 4) \cdot 3 x

\frac{125 ( - 3 + 2 )}{98}

(\frac{( x + 1 )}{x})^{2}
