expand (v-5)(v+3)(v+2)

expand

(v - 5) (v + 3) (v + 2)

v^{3} - 19 v - 30

Solution steps

(v - 5) (v + 3) (v + 2)

Expand

(v - 5) (v + 3) (v + 2) : (v^{2} - 2 v - 15) (v + 2)

= (v^{2} - 2 v - 15) (v + 2)

Distribute parentheses

= v^{2} v + v^{2} \cdot 2 - 2 vv - 2 v \cdot 2 - 15 v - 15 \cdot 2

Simplify

v^{2} v + v^{2} \cdot 2 - 2 vv - 2 v \cdot 2 - 15 v - 15 \cdot 2 : v^{3} - 19 v - 30

= v^{3} - 19 v - 30

2 cos (x) \cdot (- sin (x))

\frac{7}{x - 3} + \frac{3}{x + 5}

lo g_{2} (x - 1) - 3 lo g_{2} (x) - 2 lo g_{2} (x + 1)

(0.3)^{2} + 3.2

- (- 8)
