Write in Standard Form x-11=-5x^2

$x - 11 = - 5 x^{2}$

Add $5 x^{2}$ to both sides of the equation.

$x - 11 + 5 x^{2} = 0$

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

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

Move $- 11$ .

$x + 5 x^{2} - 11 = 0$

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

$5 x^{2} + x - 11 = 0$
