Math 116 - Chapter 2 Study Guide
- Solve the equation if possible. Look at problems 2.1.15-29.
- Solve the formula for the indicated variable. Look at problems 2.1.31-34.
- Use a graphing utility to approximate all solutions of the equation. Remember that
you're only looking for x-values here since the y-values will be zero. Look at problems
2.2.35-45. Use the root or zero feature of the calculator, do not use the arrow / zoom keys
to approximate the intercept.
- Perform the indicated operations with complex numbers and simplify. Write your
answers in standard form. Look at problems 2.3.25-36, 2.3.47-65. Four parts.
- Solve the quadratic equation by factoring. Look at problems 2.4.5-13.
- Solve the quadratic equation by extraction of roots. Look at problems 2.4.15-21.
- Solve the quadratic equation by completing the square. Look at problems 2.4.23-29.
- Solve the quadratic equation by using the quadratic formula. Look at problems 2.4.45-51.
- Use a graphing utility to approximate any points of intersection of the graphs of the
equations. You need both the x-coordinate and the y-coordinate on this problem. Look
at problems 2.2.49-53. Use the intersect feature of the calculator, do not use the arrow /
zoom keys to approximate the intersection point.
- Find all solutions of the equation. Use any algebraic method, but show work. Look at
problems 2.4.61-75, 2.4.81-86. Four parts.
- Find an equation having the given solutions. Expand your answer (don't leave it in
factored form). Look at problems 2.4.109-116.
- Solve the inequality and sketch on the real number line. Write your answers in interval
notation. Look at problems 2.5.29-36, 2.5.45-50, 2.5.55-58. Three parts.
- Some of the problems are directly from the text.
- Show enough work on all problems to convince me you know what you're doing.
- You should show work on all problems except the two that say to use the graphing
calculator. You may use the calculator to check yourself, but show work.
- There is a take home portion of the exam. The answers to the take home portion may be
found in the lecture notes on the Internet. The take home portion is worth 20 points and
is due the day of the exam.
- The in-class portion is worth 80 points.
