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

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

cos (x) x^{2} - cos (x) \cdot 1 : x^{2} cos (x) - cos (x)

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

(x + 5) l e f t (x + 2)

\frac{8}{( 1 - 3 x ) ^{2}}

\frac{( k + 1 ) ^{4}}{4}

(5 x + \frac{4}{x}) (2 x + 3)

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