Find the Perfect Square Trinomial y^2+30y

$y^{2} + 30 y$

Step 1

To find the $c$ value $c = {(\frac{b}{2})}^{2}$ , divide the coefficient of $y$ 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.

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