$- 4 x^{2} + 8 x + y - 3 = 0$

Step 1

Move all terms not containing $y$ to the right side of the equation.

Step 1.1

Add $4 x^{2}$ to both sides of the equation.

$8 x + y - 3 = 4 x^{2}$

Step 1.2

Subtract $8 x$ from both sides of the equation.

$y - 3 = 4 x^{2} - 8 x$

Step 1.3

Add $3$ to both sides of the equation.

$y = 4 x^{2} - 8 x + 3$

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 $4 x^{2} - 8 x + 3$ .

$y = 4 x^{2} - 8 x + 3$
