Question

$$- 5 + 5 ( v ^ { 2 } + 6 v - 3 ) + 4 v ^ { 2 }$$

Evaluate

$9v^{2}+30v-20$

Solution Steps

Use the distributive property to multiply $5$ by $v^{2}+6v-3$.

$$-5+5v^{2}+30v-15+4v^{2}$$

Subtract $15$ from $-5$ to get $-20$.

$$-20+5v^{2}+30v+4v^{2}$$

Combine $5v^{2}$ and $4v^{2}$ to get $9v^{2}$.

$$-20+9v^{2}+30v$$

Expand

$9v^{2}+30v-20$

Solution Steps

Use the distributive property to multiply $5$ by $v^{2}+6v-3$.

$$-5+5v^{2}+30v-15+4v^{2}$$

Subtract $15$ from $-5$ to get $-20$.

$$-20+5v^{2}+30v+4v^{2}$$

Combine $5v^{2}$ and $4v^{2}$ to get $9v^{2}$.

$$-20+9v^{2}+30v$$
