Write in Standard Form 7x+3x^2-8=-1

$7 x + 3 x^{2} - 8 = - 1$

Add $1$ to both sides of the equation.

$7 x + 3 x^{2} - 8 + 1 = 0$

Add $- 8$ and $1$ .

$7 x + 3 x^{2} - 7 = 0$

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

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

Reorder $7 x$ and $3 x^{2}$ .

$3 x^{2} + 7 x - 7 = 0$
