Find the Vertex Form p(x)=x^2-14x+29

$p (x) = x^{2} - 14 x + 29$

Step 1

Write $p (x) = x^{2} - 14 x + 29$ as an equation.

$y = x^{2} - 14 x + 29$

Step 2

Complete the square for $x^{2} - 14 x + 29$ .

Use the form $a x^{2} + b x + c$ , to find the values of $a$ , $b$ , and $c$ .

$a = 1$

$b = - 14$

$c = 29$

Consider the vertex form of a parabola.

$a {(x + d)}^{2} + e$

Find the value of $d$ using the formula $d = \frac{b}{2 a}$ .

Substitute the values of $a$ and $b$ into the formula $d = \frac{b}{2 a}$ .

$d = \frac{- 14}{2 \cdot 1}$

Cancel the common factor of $- 14$ and $2$ .

Factor $2$ out of $- 14$ .

$d = \frac{2 \cdot - 7}{2 \cdot 1}$

Cancel the common factors.

Factor $2$ out of $2 \cdot 1$ .

$d = \frac{2 \cdot - 7}{2 (1)}$

Cancel the common factor.

$d = \frac{2 \cdot - 7}{2 \cdot 1}$

Rewrite the expression.

$d = \frac{- 7}{1}$

Divide $- 7$ by $1$ .

$d = - 7$

Find the value of $e$ using the formula $e = c - \frac{b^{2}}{4 a}$ .

Substitute the values of $c$ , $b$ and $a$ into the formula $e = c - \frac{b^{2}}{4 a}$ .

$e = 29 - \frac{{(- 14)}^{2}}{4 \cdot 1}$

Simplify the right side.

Simplify each term.

Raise $- 14$ to the power of $2$ .

$e = 29 - \frac{196}{4 \cdot 1}$

Multiply $4$ by $1$ .

$e = 29 - \frac{196}{4}$

Divide $196$ by $4$ .

$e = 29 - 1 \cdot 49$

Multiply $- 1$ by $49$ .

$e = 29 - 49$

Subtract $49$ from $29$ .

$e = - 20$

Substitute the values of $a$ , $d$ , and $e$ into the vertex form ${(x - 7)}^{2} - 20$ .

${(x - 7)}^{2} - 20$

Step 3

Set $y$ equal to the new right side.

$y = {(x - 7)}^{2} - 20$
