factor 4r^2+4r+1

Solution

factor

4 r^{2} + 4 r + 1

Solution

(2 r + 1)^{2}

Solution steps

4 r^{2} + 4 r + 1

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

4 r^{2} = (2 r)^{2}

1 = 1^{2}

4 r = 2 \cdot 2 r \cdot 1

= (2 r)^{2} + 2 \cdot 2 r \cdot 1 + 1^{2}

Apply Perfect Square Formula:

a^{2} + 2 ab + b^{2} = (a + b)^{2}

(2 r)^{2} + 2 \cdot 2 r \cdot 1 + 1^{2} = (2 r + 1)^{2}

= (2 r + 1)^{2}
