expand-(2x+1)cos(5)

Solution

expand

- (2 x + 1) cos (5)

Solution

- 2 x cos (5) - cos (5)

Solution steps

- (2 x + 1) cos (5)

= - cos (5) (2 x + 1)

Apply the distributive law:

a (b + c) = ab + a c

- cos (5) (2 x + 1) = - cos (5) \cdot 2 x - cos (5) \cdot 1

= - cos (5) \cdot 2 x - cos (5) \cdot 1

Simplify

- cos (5) \cdot 2 x - cos (5) \cdot 1 : - 2 x cos (5) - cos (5)

= - 2 x cos (5) - cos (5)
