The answer is 26x squared/9 plus 13x minus four.
What are the answer options?
A rotation of 270 would be equal to 630, 990, etc. Adding 360 degrees would result in the same rotation.
A rotation of 90 degrees counter-clockwise would also result in the same rotation, as would 90 plus any multiple of 360 if rotated counter-clockwise.
