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

expand

(x^{2} - 1) x^{2} - 1

x^{2} x^{2} - 1 - x^{2} - 1

Solution steps

(x^{2} - 1) x^{2} - 1

= x^{2} - 1 (x^{2} - 1)

Apply the distributive law:

a (b - c) = ab - a c

x^{2} - 1 (x^{2} - 1) = x^{2} - 1 x^{2} - x^{2} - 1 \cdot 1

= x^{2} - 1 x^{2} - x^{2} - 1 \cdot 1

Simplify

x^{2} - 1 x^{2} - x^{2} - 1 \cdot 1 : x^{2} x^{2} - 1 - x^{2} - 1

= x^{2} x^{2} - 1 - x^{2} - 1

\frac{( ( x + 9 ) ( x - 4 ) )}{( x - 1 )}

(12 + 3) (3 + 2)

\frac{1}{s ^{n} ( s - 6 )}

(2 - i, 3 + 2 i, 1 + 3 i) (1 - 3 i, 2 + 3 i, 3 - 2 i)

\frac{11}{3} (- e^{- x} x^{2} - 2 e^{- x} x - 2 e^{- x}) (e^{x})
