Math 116 - Chapter 2 Study Guide


  1. Solve the equation if possible. Show work. Look at problems 2.1.37 - 2.1.53*. Two parts.
  2. Solve the quadratic equation by factoring. Look at problems 2.4.5 - 2.4.11*.
  3. Solve the quadratic equation by extraction of roots. Look at problems 2.4.13 - 2.4.15*.
  4. Find all solutions of the equation. Use any algebraic method, but show work. Look at problems 2.4.53 - 2.4.69*, 2.4.75-2.4.85*. Four parts. Be sure you understand how to factor an expression containing rational exponents.
  5. Perform the indicated operation and simplify. Look at problems 2.3.31 - 2.3.40*, 2.3.51 - 2.3.64*, 2.3.67 - 2.3.74*. Three parts.
  6. Solve the quadratic equation by completing the square. Look at problems 2.4.17 - 2.4.20*.
  7. Solve the quadratic equation by using the quadratic formula. Look at problems 2.4.33 - 2.4.42*.
  8. Solve the inequality and sketch on the real number line. Write your answers in interval notation. Look at problems 2.5.31 - 2.5.40*, 2.5.51 - 2.5.58*, 2.5.63 - 2.5.66*. Three parts.
  9. Use a graphing utility to approximate any solutions of the equation. Sketch an appropriate graph. Remember that you're only looking for x-values here since the y-values will be zero. Look at problems 2.2.33-2.2.44*.
  10. 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 2.2.47-2.2.60*.
