$3 v (7 v) + 3 v \cdot - 2 + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

Rewrite using the commutative property of multiplication.

$3 \cdot 7 v \cdot v + 3 v \cdot - 2 + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

Multiply $- 2$ by $3$ .

$3 \cdot 7 v \cdot v - 6 v + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

Simplify each term.

Multiply $v$ by $v$ by adding the exponents.

Move $v$ .

$3 \cdot 7 (v \cdot v) - 6 v + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

Multiply $v$ by $v$ .

$3 \cdot 7 v^{2} - 6 v + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

$21 v^{2} - 6 v + 3 (v^{2} + 2 v + 1) - 3 v (- 5 v + 3)$

Apply the distributive property.

$21 v^{2} - 6 v + 3 v^{2} + 3 (2 v) + 3 \cdot 1 - 3 v (- 5 v + 3)$

Simplify.

Multiply $2$ by $3$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 \cdot 1 - 3 v (- 5 v + 3)$

Multiply $3$ by $1$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 v (- 5 v + 3)$

Apply the distributive property.

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 v (- 5 v) - 3 v \cdot 3$

Rewrite using the commutative property of multiplication.

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 \cdot - 5 v \cdot v - 3 v \cdot 3$

Multiply $3$ by $- 3$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 \cdot - 5 v \cdot v - 9 v$

Simplify each term.

Multiply $v$ by $v$ by adding the exponents.

Move $v$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 \cdot - 5 (v \cdot v) - 9 v$

Multiply $v$ by $v$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 - 3 \cdot - 5 v^{2} - 9 v$

Multiply $- 3$ by $- 5$ .

$21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 + 15 v^{2} - 9 v$

Step 2

Simplify by adding terms.

Combine the opposite terms in $21 v^{2} - 6 v + 3 v^{2} + 6 v + 3 + 15 v^{2} - 9 v$ .

Add $- 6 v$ and $6 v$ .

$21 v^{2} + 3 v^{2} + 0 + 3 + 15 v^{2} - 9 v$

Add $21 v^{2} + 3 v^{2}$ and $0$ .

$21 v^{2} + 3 v^{2} + 3 + 15 v^{2} - 9 v$

Add $21 v^{2}$ and $3 v^{2}$ .

$24 v^{2} + 3 + 15 v^{2} - 9 v$

Add $24 v^{2}$ and $15 v^{2}$ .

$39 v^{2} + 3 - 9 v$

Move $3$ .

$39 v^{2} - 9 v + 3$

Simplify 3v(7v-2)+3(v^2+2v+1)-3v(-5v+3)
