Question

3х +2 cubes in expanded​

Answer 1

Answer:

9x³+54x²+36x+8

Step-by-step explanation:

(3x+2)³

    ↓

It is in the form of $(a+b)^{3}$ and we know that $(a+b)^{3}=a^{3}+b^{3}+3ab(a+b)$

a=3x

b=2

(3x+2)³=(3x)³+(2)³+3(3x)(2)(3x+2)

           =9x³+8+18x(3x+2)

           =9x³+8+54x²+36x

           =9x³+54x²+36x+8
