Simplify (2x+5)^2

Problem

(2*x+5)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=a2+2*a*b+b2

3. Substitute a=2*x and b=5 into the formula.

4. Expand the terms to get (2*x)2+2*(2*x)*(5)+5

5. Simplify each term by performing the multiplication and squaring.

6. Calculate the first term: (2*x)2=4*x2

7. Calculate the middle term: 2(2x)(5) = 20x$.

8. Calculate the last term: 5=25

Final Answer

(2*x+5)2=4*x2+20*x+25
