Find the Perfect Square Trinomial y^2-14y+

$y^{2} - 14 y +$

Step 1

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

Divide $14$ by $2$ .

${(- 1 \cdot 7)}^{2}$

Multiply $- 1$ by $7$ .

${(- 7)}^{2}$

Raise $- 7$ to the power of $2$ .

$49$

Step 2

Add $49$ to get the perfect square trinomial.

$y^{2} - 14 y + 49$
