Simplify (b+11)*(2b)

$(b + 11) \cdot (2 b)$

Step 1

Apply the distributive property.

$b (2 b) + 11 (2 b)$

Step 2

Simplify the expression.

Rewrite using the commutative property of multiplication.

$2 b \cdot b + 11 (2 b)$

Multiply $2$ by $11$ .

$2 b \cdot b + 22 b$

Step 3

Multiply $b$ by $b$ by adding the exponents.

Move $b$ .

$2 (b \cdot b) + 22 b$

Multiply $b$ by $b$ .

$2 b^{2} + 22 b$
