A.(x+2)pangkat 2 =

B. (4x – 2y)³ = 1.(4x)³ + 3.(4x)².-2y + 3.4x.(-2y)² + 1.(-2y)³ = 64x³ – 96x²y + 48xy² – 8y³

C.  (y+1)⁵ = 1.y⁵ + 5.y⁴.1 + 10.y³.1² + 10.y².1³ + 5.y¹.1⁴ + 1.1⁵ 
          =y⁵ + 10y³ + 10y² + 5y + 1

D.  
(-2x-3y)³= 1.(-2x)³ + 3.(-2x)².(-3y) + 3. (-2x)¹.(-3y)² + 1.(-3y)³
            = -8x³ – 36x²y – 54xy² - 27y³
