Answer:
try this answer x2 + 2xy + y2 - 16
Disagree.
b/8 = 56; multiply both sides by 8 to solve for b, and you get b = 448

The final result is,
C) 0 only.
We gathered the solutions of b = 0, -4.
b = -4 was not true so we had to remove it from the solution set, and we are left with b = 0 now. You can check this answer by substituting 0 in for b in the original equation. You should get 1 = 1, which is the correct answer.
