Question

(2x+3)^3=8x^3+36x^2+54x+27 true or false

Answer 1

Answer:

It is TRUE

Step-by-step explanation:

(2x+3)^3

Identity:- a^3+b^3+3ab(a+b)

(2x+3)^3 = (2x)^3 + (3)^3 + 3×2x×3(2x+3)

              = 8x^3 + 27 + 18x(2x+3)

              = 8x^3 + 27 + 36x^2 + 54x

              = 8x^3 + 36x^2 + 54x + 27

Thus proved that, (2x+3)^3 = 8x^3 + 36x^2 + 54x + 27

Answer 2
