Answer:
-2r^3+4r^2+12r-4
Step-by-step explanation:
6r^3-2r^2+12r-4-8r^3+6r^2
(6r^3-8r^3)+(-2r^2+6r^2)+12r-4
simplify
-2r^3+4r^3+12r-4
now, as far as the second case....well, sine of anything is within the range of -1 or 1, so -1 < sin(A) < 1
now, we have -2 = sin(A), which simply is out of range for a valid sine, so there's no angle with such sine
so, only the first case are the valid angles for A
