factor r^2+4r+4

Solution

factor

r^{2} + 4 r + 4

Solution

(r + 2)^{2}

Solution steps

r^{2} + 4 r + 4

Rewrite in the form of

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

4 = 2^{2}

4 r = 2 r \cdot 2

= r^{2} + 2 r \cdot 2 + 2^{2}

Apply Perfect Square Formula:

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

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

= (r + 2)^{2}
