Notice that each term inside the parentheses is being multiplied by the coefficient.

Distributive Property

Practice makes perfect

To identify the property being demonstrated by the given equation, we should first identify the operation being performed.

If x (y + z) = a, then x y + x z = a .

In this case, the product of

x

and a parenthetical factor is equal to the sum of the products of

x

and each term inside the parentheses. This is the Distributive Property.

x (y + z) = a

Distribute $x$

x \cdot y + x \cdot z = a

Multiply

x y + x z = a
