Question 9 • Integrated Math 2A - Mr. Katykhin 26
Rewrite the equation as x(x + 2) − 255 = 0, which factors as (x − 15)(x + 17) = 0. The zero product property gives x = 15 or x = −17. Since x represents the first integer in the pair x and x + 2, these are two possible “first” integers; their corresponding second integers are 17 and −15.
