Question

(3x-2)^3 of polynomial identity 6th and 7th of class 9th ​

Answer 1

Answer:

(3x-2)^3= (3x)^3 - (2)^3 - 3*3x*2(3x-2)

(3x-2)^3= 27x^3- 8- 18x(3x-2)

(3x-2)^3= 27x^3- 8- 54x^2- 36x

(3x-2)^2 =27x^3- 54x^2- 36x-8

Hope its help you...❤✌

Answer 2

Answer:

yes

Step-by-step explanation:

(3x–2)^3

(a–b)^3

a3+b3–3ab(a+b)

3x^3+2^3–3(3x×2)(3x+2)

27x^3+8–3(6x)(3x+2)

27x^3+8–18x(3x+2)

27x3+8–54x2+2
