  1. Look at the graph: Look at the graph to determine the number of roots and their signs.
  2. Identify roots: If the graph crosses the x-axis at b=10b=10, b=20b=20, and b=20b=-20, then the roots are b=10b=10, b=20b=20, and b=20b=-20.
  3. Write factors: Write the factors based on the roots: (b10)(b-10), (b20)(b-20), and (b+20)(b+20).
  4. Determine leading coefficient sign: Determine the sign of the leading coefficient by observing the end behavior of the graph.
  5. Observe end behavior: If the graph opens downwards, the leading coefficient is negative. If it opens upwards, the leading coefficient is positive.
