x^2+X+5=5.745

Solution for x^2+X+5=5.745 equation:

x^2+x+5=5.745

We move all terms to the left:

x^2+x+5-(5.745)=0

We add all the numbers together, and all the variables

x^2+x-0.745=0

a = 1; b = 1; c = -0.745;
Δ = b2-4ac
Δ = 12-4·1·(-0.745)
Δ = 3.98
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{-(1)-\sqrt{3.98}}{2*1}=\frac{-1-\sqrt{3.98}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{3.98}}{2*1}=\frac{-1+\sqrt{3.98}}{2}
