NAME _____________________________________________ DATE _____________________________ PERIOD _____________ Chapter 4 14 Glencoe Algebra 2 4-2 Practice Solving Quadratic Equations By Graphing Use the related graph of each equation to determine its solutions. 1. ?3?2 + 3 = 0 2. 3?2 + ? + 3 = 0 3. ?2 ? 3? + 2 = 0 Solve each equation. If exact roots cannot be found, state the consecutive integers between which the roots are located. 4. ?2?2 ? 6? + 5 = 0 5. ?2 + 10? + 24 = 0 6. 2?2 ? ? ? 6 = 0 7. ??2 + ? + 6 = 0 8. ??2 + 5? ? 8 = 0 9. GRAVITY Use the formula h(t) = ?0? ? 16? 2, where h(t) is the height of an object in feet, ?0 is the object?s initial
