Explanation:
then, and the first equation
u³ -u³+u³.(do not write it. just for fun)
(2x - y)³ --:
(2x)³ - 3×4x²b +3y²×2x -(y³)
(2x)³ - 3×4x²b +3y²×2x -(y³)8x³ - 12x²y + 6xy² -y³
(2x)³ - 3×4x²b +3y²×2x -(y³)8x³ - 12x²y + 6xy² -y³second equation,
-(x+y )whole cube
= (x-y)³
-(x³ + 3x²y +3y²x +y³)
TtHhEeNn 3rd equation,
(2y- x )² ::--
(2y)³ - 3×x²× 2y + 3 ×(2y²) × x -(x)³
= 8y³ -6x²y +12y²x - x³
then all the equation at onse:::---
=8x³ - 12x²y + 6xy² -y³-(x³ + 3x²y +3y²x +y³) + 8y³ -6x²y +12y²x - x³
= 8x³ - 12x²y + 6xy² -y³-x³ - 3x²y -3y²x -y³ + 8y³ -6x²y +12y²x - x³
= 8x³ -21x²y + 21y²x 2y³(this is the correct answer)
