Writing Equivalent Expressions
How can you use the Distributive Property to write equivalent algebraic expressions?
2
Use the Distibutive Property to write an Equivalent Expression.
3
2(3x−1)
3x - 1 is being multiplied by 2. The 2 must multiply everything inside of the paranthesis.
Which terms are multiplied together first? (2 and 3x)
2⋅3x=6x
Which terms are multiplied next? (2 and -1)
2⋅−1=−2
So, the expression equals 6x - 2.
4
Check your work: Are these equal?
2(3x−1)=6x−2Choose a value for x. (x = 2)
Substitute and evaluate each expression.
2(3⋅2−1) = 2(6−1) = 2(5) = 10
6⋅2−2 = 12−2 = 10
Yes. These are equal.
