Answer:
below
Step-by-step explanation:
The answer of the first expert is correct, this is from Pascal triangle 5th level.
shown in the attached picture, when we extend the brackets the whole function will become...
f(x) = 1*(4x)⁵(-2y)⁰ + 5*(4x)⁴(-2y)¹ + 10*(4x)³(-2y)² + 10* (4x)²(-2y)³ + 5*(4x)¹(-2y)⁴ + 1*(4x)⁰(-2y)⁵
= (4x - 2y)⁵
