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

expand

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

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

Solution steps

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

= 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)

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