Step 1.1.1

Subtract $x^{2}$ from both sides of the equation.

$10 x - y + 29 = - x^{2}$

Step 1.1.2

Subtract $10 x$ from both sides of the equation.

$- y + 29 = - x^{2} - 10 x$

Step 1.1.3

Subtract $29$ from both sides of the equation.

$- y = - x^{2} - 10 x - 29$

Step 1.2

Divide each term in $- y = - x^{2} - 10 x - 29$ by $- 1$ and simplify.

Step 1.2.1

Divide each term in $- y = - x^{2} - 10 x - 29$ by $- 1$ .

$\frac{- y}{- 1} = \frac{- x^{2}}{- 1} + \frac{- 10 x}{- 1} + \frac{- 29}{- 1}$

Step 1.2.2

Simplify the left side.

Step 1.2.2.1

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{- x^{2}}{- 1} + \frac{- 10 x}{- 1} + \frac{- 29}{- 1}$

Step 1.2.2.2

Divide $y$ by $1$ .

$y = \frac{- x^{2}}{- 1} + \frac{- 10 x}{- 1} + \frac{- 29}{- 1}$

Step 1.2.3.1.1

Dividing two negative values results in a positive value.

$y = \frac{x^{2}}{1} + \frac{- 10 x}{- 1} + \frac{- 29}{- 1}$

Step 1.2.3.1.2

Divide $x^{2}$ by $1$ .

$y = x^{2} + \frac{- 10 x}{- 1} + \frac{- 29}{- 1}$

Step 1.2.3.1.3

Move the negative one from the denominator of $\frac{- 10 x}{- 1}$ .

$y = x^{2} - 1 \cdot (- 10 x) + \frac{- 29}{- 1}$

Step 1.2.3.1.4

Rewrite $- 1 \cdot (- 10 x)$ as $- (- 10 x)$ .

$y = x^{2} - (- 10 x) + \frac{- 29}{- 1}$

Step 1.2.3.1.5

Multiply $- 10$ by $- 1$ .

$y = x^{2} + 10 x + \frac{- 29}{- 1}$

Step 1.2.3.1.6

Divide $- 29$ by $- 1$ .

$y = x^{2} + 10 x + 29$

Step 2

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$y = a x^{2} + b x + c$

Step 3

The standard form is $x^{2} + 10 x + 29$ .

$y = x^{2} + 10 x + 29$
