Question

1. Expand
(i) (3x + 2)^3​

Answer 1

Answer:

$= {(3x + 2)}^{3} \\ = 27 {x}^{3} + 54 {x}^{2} + 36x + 8$

Answer 2

Answer:

(x+y)^3= x³+y³+3xy(x+y)

x+y)^3= x³+y³+3xy(x+y)(3x)^3+(2)^3+3(3x×2)(3x+2)

x+y)^3= x³+y³+3xy(x+y)(3x)^3+(2)^3+3(3x×2)(3x+2)9x³+8+18x(3x+2)

x+y)^3= x³+y³+3xy(x+y)(3x)^3+(2)^3+3(3x×2)(3x+2)9x³+8+18x(3x+2)9x³+8+54x+36

x+y)^3= x³+y³+3xy(x+y)(3x)^3+(2)^3+3(3x×2)(3x+2)9x³+8+18x(3x+2)9x³+8+54x+369x³+54x+44

x+y)^3= x³+y³+3xy(x+y)(3x)^3+(2)^3+3(3x×2)(3x+2)9x³+8+18x(3x+2)9x³+8+54x+369x³+54x+44Hope this will help you
