When you use the distributive property, you multiply the two numbers together, just like simplifying any product. But we can also apply the distributive property in the other direction, then calling out a common factor, and thus: Examples : 6(2 + 4) = 6(2) + 6(4) 8(5 - 3) = 8(5) - 8(3) Writing Equivalent Expressions Using Distributive Property - Examples. Since each term of the expression has a factor of 2, we can "factor out" a 2 from each term to find that 2x + 4y = 2(x + 2y). Distributive Property; Well, the distributive property is that by which the multiplication of a number by a sum will give us the same as the sum of each of the sums multiplied by that number.
