A quadratic equation is written in the form:
$ax^2 + bx + c = 0$

The given equation $5-10x-3x^2=0$ can be rewritten as $-3x^2-10x+5=0$

Where:
$a=-3$
$b=-10$
$c=5$

The quadratic formula can be used to find the roots of any quadratic equation.

$x= (-b+- sqrt(b^2-4ac))/(2a)$

So I encourage you to plug in the values from this equation and simplify.

The answers should be $x = -3.77485 and x= 0.441518$
