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)

You can put this solution on YOUR website!
That synthetic division gives remainder 7, and this shows that f%28-1%29=7. The effect is well described in The Remainder Theorem.
