Write in Standard Form 8x^2=8x+13+4x^2

$8 x^{2} = 8 x + 13 + 4 x^{2}$

Move all the expressions to the left side of the equation.

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

$8 x^{2} - 8 x = 13 + 4 x^{2}$

Subtract $13$ from both sides of the equation.

$8 x^{2} - 8 x - 13 = 4 x^{2}$

Subtract $4 x^{2}$ from both sides of the equation.

$8 x^{2} - 8 x - 13 - 4 x^{2} = 0$

Subtract $4 x^{2}$ from $8 x^{2}$ .

$4 x^{2} - 8 x - 13 = 0$

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

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

The standard form is $4 x^{2} - 8 x - 13$ .

$4 x^{2} - 8 x - 13 = 0$
