expand (x+1)sqrt(x-1)

expand

(x + 1) x - 1

x x - 1 + x - 1

Solution steps

(x + 1) x - 1

= x - 1 (x + 1)

Apply the distributive law:

a (b + c) = ab + a c

x - 1 (x + 1) = x - 1 x + x - 1 \cdot 1

= x - 1 x + x - 1 \cdot 1

Simplify

x - 1 x + x - 1 \cdot 1 : x x - 1 + x - 1

= x x - 1 + x - 1

(9 x^{\frac{3}{2}} - 3 x^{\frac{5}{2}})^{2}

(sin (y)) (x + sin (y)) d x + 2 x^{2} cos (y) d y

\frac{1}{2} (6 e - 3 f - 43)

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

d (\frac{a}{x} + arctan (\frac{x}{a}))
