2nd TRY: Simplifying Expressions with Negatives

Tackle negative numbers in algebraic expressions! Practice distributing and combining terms.

This is your 2nd attempt. Make sure you have completed the 1st try and made corrections for the questions that you missed before taking this attempt. REVIEW PRACTICE: Distributing with Positive Numbers! Match the factored form to the distributed (expanded) form. 6(y+5x) 6y + 30x 6(2x + 5y) 12x + 30y 6(x + y) 6x + 6y 6(2x- 5) 12x - 30 1 - 30) x - 15 Now Let's Practice with Some Negative Numbers! PAY ATTENTION TO YOUR INTEGER RULES!!! 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 Which answer choice correctly shows the expanded form of:-8(-3c+9)? 24c-72 24c+72 24c+9 -24c-72 -24c+72 -24c+9 Which answer choice correctly shows the expanded form of:-8(3c-9)? 24c-72 24c+72 24c+9 -24c-72 -24c+72 -24c+9
