Question 1037692: Paula used synthetic division to divide the polynomial f(x) by x + 1, as shown:
-1| -2 -5 4
2 3
|___________
-2 -3 7
What is the value of f(-1)?

If anyone can help me again thanks! (The numbers and everything aren't lining up correctly hopefully you'll know what i'm talking about)
