Lesson 17 Student Outcomes

Students learn that equations of the form (x - a)(x - b) = 0 have the same solution set as two equations joined by “or”: x - a = 0 or x - b = 0.

Students solve factored or easily factorable equations.

Lesson 17 Summary

The zero-product property says that If ab = 0, then either a = 0 or b = 0 or a = b = 0.

Exit Ticket

1. Find the solution set to the equation 3x2 + 27x = 0

2. Determine if each statement is true or false. If the statement is false, explain why or show work proving that it is false.

a. If a = 5 then ac = 5c

b. If ac = 5c then a = 5
