expand (s-1)(s+2)(s+3)

expand

(s - 1) (s + 2) (s + 3)

s^{3} + 4 s^{2} + s - 6

Solution steps

(s - 1) (s + 2) (s + 3)

Expand

(s - 1) (s + 2) (s + 3) : (s^{2} + s - 2) (s + 3)

= (s^{2} + s - 2) (s + 3)

Distribute parentheses

= s^{2} s + s^{2} \cdot 3 + ss + s \cdot 3 - 2 s - 2 \cdot 3

Simplify

s^{2} s + s^{2} \cdot 3 + ss + s \cdot 3 - 2 s - 2 \cdot 3 : s^{3} + 4 s^{2} + s - 6

= s^{3} + 4 s^{2} + s - 6

\frac{sin ( x )}{cos ^{3} ( x )}

\frac{2 x + 8}{x ^{2} + 6 x + 8} + \frac{1}{x + 2}

4 \cdot 4 \cdot 3

(- 5) - (- 3)

10 + \frac{1}{5}
