1. Suppose you get a job selling T-shirts at a concert. You get $2 for each T-shirt you sell, but it costs you $5 to get into the concert. How many T-shirts will you have to sell in order to make $25?

2. Solve for *x* and check. 2(*x* - 1) + 4 = 3*x* - (2*x* - 3)

3. (2*x*^{2} - 3*x* + 5) + (*x*^{2} + 4*x* - 6)

4. (2*x*^{2} - 3*x* + 5) - (*x*^{2} + 4*x* - 6)

5. (2*x*^{2} - 3*x* + 5)(*x*^{2} + 4*x* - 6)

6. (2*x*^{2} - 3*x* + 5)/(*x*^{2} + 4*x* - 6)

In #6, use long division of polynomials.

7. Solve for *x* and check. 2*x*^{2} + *x* = 21

8. Divide
