ACT Challenge Question 12: What is S?

Magoosh ACT Challenge Question

The Algebra Song is currently stuck in my head, so I thought I’d share a tough ACT Math algebra problem with you this week. (If you clicked on the link–you’re welcome.)

Can you solve it? We’ll post the answer later this week, but if you think you have the perfect approach to this problem, post it in the comments below–your solution may just get featured!

What would s have to be so that {x^3} + {5x^2} + sx + 6 is divisible by (x + 2)?

  1. 9
  2. 5
  3. 2
  4. -6
  5. -13
