Find the Perfect Square Trinomial z^2+22z

$z^{2} + 22 z$

Step 1

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

Divide $22$ by $2$ .

$11^{2}$

Raise $11$ to the power of $2$ .

$121$

Step 2

Add $121$ to get the perfect square trinomial.

$z^{2} + 22 z + 121$
