Using the distributive property to simplify expressions

• How can you use the distributive property to write variable expressions without parentheses and simplify the result?
• How can you use the distributive property to re-write 4(x + y) without parentheses?
• How can you use the distributive property to re-write 5(3x - 7) without parentheses?
• How can you use the distributive property to re-write -3(x + 10) without parentheses?
• How can you use the distributive property to re-write -3(2x - 4) without parentheses?
• How can you use the distributive property to re-write -(x + 8) without parentheses?
• How can you use the distributive property to re-write -(-2x - 1) without parentheses?
• How can you use the distributive property to re-write 2/7(35x - 14) without parentheses?
• How can you use the distributive property to re-write 2(3x - 1) - (-20) without parentheses?
• How can you simplify an expression when you cannot simplify inside of parentheses?
This lesson shows how to use the distributive property in a very useful way - rewriting variable expressions without parentheses. This skill becomes very useful in future problems in Algebra.
