• (2y - 5)^3

• (2 - 2y)^3

AYUDA!!!

Answer 1

Formulas binomio al cubo
(a+b)³=a³+3a²b+3ab²+b³
(a-b)³=a³-3a²b+3ab²-b³
•(3x+3)³=
(3x)³+3(3x)²(3)+3(3x)(3)²+3³
27x³+3(9x²)(3)+9x(9)+27
27x³+81x²+81x+27

•(2y-5)³=
(2y)³-3(2y)²(5)+3(2y)(5)²-(5)³
8y³-3(4y²)(5)+6y(25)-125
8y³-60y²+150y-125

•(2-2y)³
(2)³-3(2)²(2y)+3(2)(2y)²-(2y)³
8-6y(4)+6(4y²)-8y³
8-24y+24y²-8y³ ordenamos
-8y³+24y²-24y+8
espero q sea d ayuda
