WHO HAS THE ANSWER!! I DONT GET IT. PLEASE COMMENT THE ANSWER ON MY POST
4+3n^2 only has two terms since 4 is one term and 3n^2 is another. They each have their individual coefficients and powers.
Well a circle has 360 degrees and this question wants the degree of counter-clockwise.
I think first we subtract 69 from 360, since that is the rotation clockwise, to get the angle of rotation.
360 - 69 is 291 degrees
the answer is 16a2-4a+4a-1
it can be simplified to 16a2-1, which can be factored to
(4a+1)(4a-1)
