Simplifying Algebraic Expressions

Matching! Match the factored form to the distributed (expanded) form. -4(x + 3) -4x - 12 4(x + 3) 4x + 12 -4(x - 3) -4x + 12 4(x - 3) 4x - 12 Sometimes a variable expression can be simplified, while other times it cannot be simplified. You are now going to sort expressions according to whether or not they can be simplified. To answer, click on each of the 8 items and a drop-down box will appear. If you make a mistake, click the "x" next to the item and you can re-do your original answer. Remember: You can only combine like terms. Like terms are two or more terms in an expression that have the same variable raised to the same power. CAN be simplified 9 + 5 9x + 5x -8y - 5y 6x2 - 10 x2 CANNOT be simplified 7y + (-3x) -8y - 14 -4y + 4y2 a + b + c #1.
