Factor 4x^2+4x+1

Problem

4*x2+4*x+1

Solution

1. Identify the structure of the quadratic expression, which is in the form a*x2+b*x+c where a=4 b=4 and c=1

2. Recognize that the first term 4*x2 is a perfect square, (2*x)2 and the last term 1 is also a perfect square, 1

3. Check if the middle term 4*x matches the pattern for a perfect square trinomial a2+2*a*b+b2 where 2*a*b=2*(2*x)*(1)=4*x

4. Apply the perfect square trinomial formula a2+2*a*b+b2=(a+b)2 using a=2*x and b=1

Final Answer

4*x2+4*x+1=(2*x+1)2
