Question

(×+3y)³ porfa
(2x-2y)³
(2x-y)³​

Answer 1

Respuesta:

1-x³ - 3(x)²(3y)+ 3(x)(3y)² -(3y)³

x³ - 9x²y + 3x(9y²) - 27y³

x³ -9x²y +27xy² -27y³

2-(2x + 3y)³ =

(2x)³ + 3*(2x)² * 3y + 3*2x*(3y)² + (3y)³ =

8x³ + 3 * 4x² * 3y + 3*2x*9y² + 27y³ =

8x³ + 36x²y + 54xy² + 27y³

3-(2x - y)³

= (2x)³ + 3(2x)²(-y) + 3(2x)(-y)² + (-y)³

= 2³x³ + 3(2²x²)(-y) + 6xy² - y³

= 8x³ + (-3y)(4x²) + 6xy² - y³

= 8x³ - 12x²y + 6xy² - y³
