LET’S TRY ONE
Solve (x − 2)(x − 5) = 0.
2 and 5
Set each factor to zero: x = 2 or x = 5.
Learning steps & teaching tips
Use the zero-product property to find both roots.
- If a product is zero, at least one factor equals zero.
- Work through the example. Explain how its evidence supports the answer.
- Try a new question; use the explanation to check your thinking.
Try it together
Write or draw your own example with different numbers. Solve it, then ask a partner to check the method as well as the answer.
If a product is zero, at least one factor equals zero.
