$7 x + 15 + x^{2} = - 1$

Step 1

Add $1$ to both sides of the equation.

$7 x + 15 + x^{2} + 1 = 0$

Step 2

Add $15$ and $1$ .

$7 x + x^{2} + 16 = 0$

Step 3

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

$a x^{2} + b x + c = 0$

Step 4

Reorder $7 x$ and $x^{2}$ .

$x^{2} + 7 x + 16 = 0$
