Find the Perfect Square Trinomial c^2-30c+

$c^{2} - 30 c +$

Step 1

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

Divide $30$ by $2$ .

${(- 1 \cdot 15)}^{2}$

Multiply $- 1$ by $15$ .

${(- 15)}^{2}$

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

$225$

Step 2

Add $225$ to get the perfect square trinomial.

$c^{2} - 30 c + 225$
