Question 1011717
If x^2 - 3x + 2k is divided by x+2, the remainder is 7. What is k? 
:
using synthetic division
......_______________
 -2 |1 - 3 + 2k
.........- 2 + 10
......----------
..,,...1 - 5 + 7
then we can write the equation
2k + 10 = 7
2k = 7 - 10
2k = -3
k = -1.5
:
Our equation is: x^2 - 3x - 3
