# How do you simplify (a + 7)2?

Oct 29, 2015

$2 a + 14$

#### Explanation:

You use the Distributive Property. This property states that a constant (which, in this case, is $2$) multiplied by an expression in parentheses or brackets (this is the $a + 7$ part for your problem) is the constant multiplied by every term in the expression.

Put into math, the Distributive Property looks like this for your problem:

$\left(a + 7\right) 2$

$= a \left(2\right) + 7 \left(2\right)$

$= 2 a + 14$

$\left(a + 7\right) 2 = 2 a + 14$

#### Explanation:

$\left(a + 7\right) 2$

Distribute the $2$.

$\left(2 \times a\right) + \left(2 \times 7\right)$

Simplify.

$2 a + 14$
