Question

expand (2x+3y) ³ say fast as possible ​

Answer 1

$question = (2x + 3y)^{3} . \\ \\ solution. \\ \\ = (2x + 3y)^{3} \\ \\ = {(2x)}^{3} + {(3y)}^{3} + 3(2x)(3y)(2x + 3y) \\ \\ = 8 {x}^{3} + 27 {y}^{3} + 18xy(2x + 3y) \\ \\ = 8 {x}^{3} + 27 {y}^{3} + 36 {x}^{2} y + 54x {y}^{2} \\ \: \: is \: the \: answer \: \: \\ hope \: it \: help \: you \:$

Answer 2

(2x+3y)³= (2x)³+3*(2x)²*3y+3*2x*(3y)²+(3y)³          [(a+b)³ = a³+3a²b+3ab²+b³]

= 8x³+36x²y+54xy²+27y³
