1. Replace 𝒇 𝒙 with 0
2. Write a, b, and c from the equation
3. Find two integers that…
• Multiply to a×c
AND
• Add to b
4. Rewrite the function – split b using
the integers from Step 3
5. Make a “reverse” Multiplication
Frame…and “undo” it
6. Let each factor = 0
7. Solve for x
8. Write the x-intercepts
