Problem

(x+2)^2

Solution

1. Identify the expression as a square of a binomial in the form (a+b)^2

2. Apply the formula for the square of a binomial, which is (a+b)^2=a^2+2*a*b+b^2

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

4. Expand the terms to get x^2+2*(x)*(2)+2^2

5. Simplify the constants and coefficients to reach the final polynomial.

Final Answer

(x+2)^2=x^2+4*x+4
