Question

(x+2)3 (small 3 not big) =
can anyone explain me how to solve this question plz?
what do i have to do?

Answer 1

$(x + 2) {}^{3} = x {}^{3} + (2) {}^{3} + 3(x) {}^{2} (2) + 3x(2) {}^{2} \\ x {}^{3} + 8 + 6x {}^{2} + 12x$

Answer 2

It is x^3+2^3+3*2*x^2+3*2^2*x

Because it’s an identity of Class 9th
And also (a+2)^3 = (a+2)(a+2)(a+2) and when we solve it we got the same answer
