expand l(-5e^{-2t}+cos(8t)+1)

expand

l (- 5 e^{- 2 t} + cos (8 t) + 1)

- 5 l e^{- 2 t} + l cos (8 t) + l

Solution steps

l (- 5 e^{- 2 t} + cos (8 t) + 1)

Distribute parentheses

= l (- 5 e^{- 2 t}) + l cos (8 t) + l \cdot 1

Apply minus-plus rules

+ (- a) = - a

= - 5 l e^{- 2 t} + l cos (8 t) + 1 \cdot l

Multiply:

1 \cdot l = l

= - 5 l e^{- 2 t} + l cos (8 t) + l

\frac{4 ( x - 2 )}{( x + 3 ) ^{3}}

\frac{x y ^{2}}{\frac{y}{3} \cdot \frac{1}{3 x}}

A (- 1, - 2)

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

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