Find the Perfect Square Trinomial z^2+30z

$z^{2} + 30 z$

Step 1

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

Divide $30$ by $2$ .

$15^{2}$

Raise $15$ to the power of $2$ .

$225$

Step 2

Add $225$ to get the perfect square trinomial.

$z^{2} + 30 z + 225$
