Factor y^2+4y+4

Problem

y2+4*y+4

Solution

1. Identify the expression as a quadratic trinomial of the form a*y2+b*y+c where a=1 b=4 and c=4

2. Recognize that the expression follows the pattern of a perfect square trinomial, a2+2*a*b+b2=(a+b)2

3. Determine the square roots of the first and last terms: √(,y2)=y and √(,4)=2

4. Verify the middle term by calculating 2⋅y⋅2=4*y which matches the given expression.

5. Write the factored form as the square of the sum of these roots.

Final Answer

y2+4*y+4=(y+2)2
