To use the distributive property, we need to understand the formula to use it. This formula will ensure that you can easily solve any equation.

The distributive property is A(B + C) = AB + AC, where AB is the product of the values A and B and AC is the product of the values A and C.

First, let's notice that we are distributing a 2 into the parentheses, so we will mark this as our A value.

Then, our two values inside the parentheses are B and C respectfully.
