expand e^{rt}(r^3-3r^2+2r)

expand

e^{r t} (r^{3} - 3 r^{2} + 2 r)

r^{3} e^{r t} - 3 r^{2} e^{r t} + 2 r e^{r t}

Solution steps

e^{r t} (r^{3} - 3 r^{2} + 2 r)

Distribute parentheses

= e^{r t} r^{3} + e^{r t} (- 3 r^{2}) + e^{r t} \cdot 2 r

Apply minus-plus rules

+ (- a) = - a

= r^{3} e^{r t} - 3 r^{2} e^{r t} + 2 r e^{r t}

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

(a + b + c + d + e + f + g + h + i)^{2}

(\frac{40 - x}{2})^{2}

(x - 4) + (2 x - 2)

(x y - 2 x + 4 y - 8) d y
