If the difference between the roots of the equation Ax2+BX+C = 0 is 4,

1.	If the difference between the roots of the equation Ax2+BX+C = 0 is 4, then which of the following is TRUE?
A.	$$B^2 - 16A^2 = 4AC + 4B^2 $$
B.	$$B^2 - 10A^2 = 4AC + 6A^2$$
C.	$$B^2 - 8A^2 = 4AC + 10A^2 $$
D.	$$B^2 - 16A^2 = 4A^C + 8B^2$$
Answer» C. $$B^2 - 8A^2 = 4AC + 10A^2 $$
