Copy and simplify the following expressions by combining like terms, making zeros, and using the Distributive Property. Using algebra tiles may be helpful.

*7-34 HW eTool*(CPM). Homework Help ✎(–1) + 4

*x*+ 2 + 2*x*+*x*–8

*x*+ 4 + (–3) + 10*x*(–4) + 1

*x*^{2}+ 3*x*+ 42(3

*x*– 2)

Group similar terms together in order to combine like terms.

(4*x* + 2*x* + *x*) + (−1 + 2)

7*x* + 1

Visualize 8 negative *x* tiles, 4 positive unit tiles, 3 negative unit tiles, and 10 positive *x* tiles. If a negative and a positive tile of the same value make a zero, how many tiles are remaining?

Group similar terms together and make zeros.

(−4 + 4) + 1*x*^{2} + 3*x*

Now the fours make a zero.

0 + 1x² + 3x

*x*^{2} + 3*x*

Distribute the 2 on the outside to each of the terms inside the parentheses.

2(3*x*) − 2(2)

Simplify.
