Simplify (2+h)^3

Problem

(2+h)3

Solution

1. Identify the expression as a binomial raised to the third power, which follows the pattern (a+b)3

2. Apply the formula for the cube of a binomial: (a+b)3=a3+3*a2*b+3*a*b2+b3

3. Substitute a=2 and b=h into the formula.

4. Calculate the first term: 2=8

5. Calculate the second term: 3*(2)*(h)=3*(4)*(h)=12*h

6. Calculate the third term: 3*(2)*(h2)=6*h2

7. Calculate the fourth term: h3

8. Combine all the terms into a single polynomial expression.

Final Answer

(2+h)3=8+12*h+6*h2+h3
