Answer 2

Answer:

Plz MARK as BRAIN LISTS answer

Step-by-step explanation:

We know by identity that:-

(a+b)^{3} = a^{3} + b^{3} + 3ab^{2} + 3a^{2} b(a+b)3=a3+b3+3ab2+3a2b 

Put a = 2x

And

b = 3

Now that you have the values of a and b, putting them in the formula, we get;

(2x+3)^{3} = (2x)^{3} + 3^{3} + 3(2x)(3)^{2} + 3(2x)^{2}(3)(2x+3)3=(2x)3+33+3(2x)(3)2+3(2x)2(3) 

Solve it further and there will be your answer;

=》 (2x+3)^{3} = 8x^{3} + 27 + 54x + 36x^{2}(2x+3)3=8x3+27+54x+36x2 

Now that you've got your answer, just simplify it by putting all the terms in descending order in accordance to their powers:-

=》 (2x+3)^{3} = 8x^{3} + 36x^{2} + 54x + 27(2x+3)3=8x3+36x2+54x+27 

We've just used the identity we knew! I had mentioned the identity at the very starting of the answer. You can see it. Just put the values and solve it :)
