Copy and simplify the following expressions by combining like terms. Using or drawing sketches of algebra tiles may be helpful. Homework Help ✎

2

*x*+ 3*x*+ 3 + 4*x*^{2}+ 10 +*x*Add like terms.

4

*x*^{2}+ (2*x*+ 3*x*+*x*) + (10 + 3)

4*x*^{2}+ 6*x*+ 134

*x*^{2}+ 6*x*+ 13

4

*x*+ 4*y*^{2}+*y*^{2}+ 9 + 10 +*x*+ 3*x*It may helpful to rearrange the terms so that all like terms are next to one another before simplifying. Remember to double check your work.

*x*^{2}+ 30 + 3*x*^{2}+ 4*x*^{2}+ 14 +*x*Try thinking of these as algebra tiles. Can you combine

*x*^{2}-tiles with x-tiles or unit tiles? If it helps you, you can use algebra tiles to help you solve this problem.

20 + 5

*xy*+ 4*y*^{2}+ 10 +*y*^{2}+*xy*Follow the steps outlined in part (a) and the hints from parts (b) and (c).

5

*y*^{2}+ 6*xy*+ 30
