-x^2+2x+182=0

Solution for -x^2+2x+182=0 equation:

-x^2+2x+182=0

We add all the numbers together, and all the variables

-1x^2+2x+182=0

a = -1; b = 2; c = +182;
Δ = b2-4ac
Δ = 22-4·(-1)·182
Δ = 732
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{732}=\sqrt{4*183}=\sqrt{4}*\sqrt{183}=2\sqrt{183}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{183}}{2*-1}=\frac{-2-2\sqrt{183}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{183}}{2*-1}=\frac{-2+2\sqrt{183}}{-2}
