Find the Perfect Square Trinomial r^2+12r

$r^{2} + 12 r$

Step 1

To find the $c$ value $c = {(\frac{b}{2})}^{2}$ , divide the coefficient of $r$ by $2$ and square the result.

Divide $12$ by $2$ .

$6^{2}$

Raise $6$ to the power of $2$ .

$36$

Step 2

Add $36$ to get the perfect square trinomial.

$r^{2} + 12 r + 36$
