Answer:
x 3 y 6 − 64
is the difference of two cubes and can be factored in the following pattern.
a 3 − b 3 = ( a − b ) ( a 2 + a b + b 2 )
a 3
factors to a
b 3
factors to b
The pattern of the signs follows the acronym SOAP
S = same sign as the cubes
O = opposite sins of the cubes
AP = always positive
x 3 y 3
factors to xy
64
factors to 4
x 3 y 3 − 64 = ( x y − 4 ) ( x 2 y 2 + 4 x y + 16 )
