We have
First, we can combine like terms 3y and -7y to get -4y.
Then, we have
We could then subtract 8 on both sides to get 
Finally, we isolate y completely by dividing both sides by -4, to get

Correct Answer:
3rd option is the correct answer
Solution:
The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:
The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:
The final equation of the polynomial becomes:
