factor r^2-12r+36

Solution

factor

r^{2} - 12 r + 36

Solution

(r - 6)^{2}

Solution steps

r^{2} - 12 r + 36

Rewrite in the form of

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

36 = 6^{2}

- 12 r = - 2 r \cdot 6

= r^{2} - 2 r \cdot 6 + 6^{2}

Apply Perfect Square Formula:

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

r^{2} - 2 r \cdot 6 + 6^{2} = (r - 6)^{2}

= (r - 6)^{2}
