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

$u^{2} - 14 u +$

Step 1

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

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