Solve the equation
(x+8)(x+9)=0

x = -8        x=-9

Step-by-step explanation:

(x+8)(x+9)=0

We can use the zero product property

x+8 = 0     x+9=0

x = -8        x=-9

If (x + 8)(x + 9) = 0, that means that either x + 8 = 0 or x + 9 = 0.

Solving each equation for x, we find that x = -8 or x = -9.

Write your answer as the set of numbers {-8, -9}.

A common mistake in this problem is for students to see

that (x + 8)(x + 9) = 0 and to say that the answer therefore is 8 or 9.

Note however that the sign of each

number switches in your final answer.
