First, note that 
Then use the formula for the sum of perfect cubes:
Therefore,
The quadratic trinomial 
couldn't be factored anymore, so the expression 
has two factors 
and 
Answer: correct choice is A.

I’m pretty sure the answer is B
(Hope this helps!!) Can I pls have brainliest??
Slope of a line contatining the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
so slope between (-6,3) and (2,-5) is
(-5-3)/(2-(-6))=(-8)/(2+6)=-8/8=-1
the slope is -1
