factor r^2+2r+1

Solution

factor

r^{2} + 2 r + 1

Solution

(r + 1)^{2}

Solution steps

r^{2} + 2 r + 1

Rewrite in the form of

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

1 = 1^{2}

2 r = 2 r \cdot 1

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

Apply Perfect Square Formula:

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

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

= (r + 1)^{2}
