simplify (t^2-2t)*(-3cos(t))

simplify

(t^{2} - 2 t) \cdot (- 3 cos (t))

- 3 cos (t) (t^{2} - 2 t)

Solution steps

(t^{2} - 2 t) (- 3 cos (t))

Apply rule:

a (- b) = - ab

(t^{2} - 2 t) (- 3 cos (t)) = - (t^{2} - 2 t) \cdot 3 cos (t)

= - (t^{2} - 2 t) \cdot 3 cos (t)

= - 3 cos (t) (t^{2} - 2 t)

\frac{( s + 1 ) ( s + 2 )}{( s + 3 ) ( s + 4 )}

\frac{x + 2}{( v - 6 ) ( v + 2 )}

(t^{2} - 8 t + 19) e^{s t}

x (156 - \frac{x}{10})

(a 2 + b 3)^{2}
