Write in Standard Form 7-5x=3x^2

$7 - 5 x = 3 x^{2}$

Subtract $3 x^{2}$ from both sides of the equation.

$7 - 5 x - 3 x^{2} = 0$

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

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

Move $7$ .

$- 5 x - 3 x^{2} + 7 = 0$

Reorder $- 5 x$ and $- 3 x^{2}$ .

$- 3 x^{2} - 5 x + 7 = 0$
