Explanation:

We can seperate the problem into two steps:

We then combine the two parts:

### Example Question #1 : Distributive Property

Distribute .

Explanation:

When distributing with negative numbers we must remember to distribute the negative to all of the variables in the parentheses.

Distribute the  through the parentheses by multiplying it with each object in the parentheses to get .

Perform the multiplication remembering the positive/negative rules to get , our answer.

### Example Question #1 : How To Use The Distributive Property In Pre Algebra

Simplify the following expression:

Explanation:

Recall that the distributive property requires that we multiply the outside term by both terms in parentheses and add the results.

### Example Question #2 : How To Use The Distributive Property In Pre Algebra

Evaluate the following expression:

None of the above

Explanation:

Recall the distributive property. We need to multiply the outside factor by both terms inside and then combine.

Thus,

### Example Question #1 : How To Use The Distributive Property In Pre Algebra

Distribute:

Explanation:

When distributing with negative numbers we must remember to distribute the negative to all of the terms in the parentheses.

Remember, a negative multiplied by a negative is positive, and a negative multiplied by a positive number is negative.

Distribute the  through the parentheses:

Perform the multiplication, remembering the positive/negative rules:

### Example Question #1 : Distributive Property

Which of the following is equivalent to ?

Explanation:

We need to distribute -3 by multiplying both terms inside the parentheses by -3.:

.

Now we can multiply and simplify. Remember that multiplying two negative numbers results in a positive number:
