x^2+745x-745=0

Solution for x^2+745x-745=0 equation:

x^2+745x-745=0

a = 1; b = 745; c = -745;
Δ = b2-4ac
Δ = 7452-4·1·(-745)
Δ = 558005
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(745)-\sqrt{558005}}{2*1}=\frac{-745-\sqrt{558005}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(745)+\sqrt{558005}}{2*1}=\frac{-745+\sqrt{558005}}{2}
